ALSA: usb-audio: Fix init call orders for UAC1
commit 5fadc941d07530d681f3b7ec91e56d8445bc3825 upstream.
There have been reports of USB-audio driver spewing errors at the
probe time on a few devices like Jabra and Logitech. The suggested
fix there couldn't be applied as is, unfortunately, because it'll
likely break other devices.
But, the patch suggested an interesting point: looking at the current
init code in stream.c, one may notice that it does initialize
differently from the device setup in endpoint.c. Namely, for UAC1, we
should call snd_usb_init_pitch() and snd_usb_init_sample_rate() after
setting the interface, while the init sequence at parsing calls them
before setting the interface blindly.
This patch changes the init sequence at parsing for UAC1 (and other
devices that need a similar behavior) to be aligned with the rest of
the code, setting the interface at first. And, this fixes the
long-standing problems on a few UAC1 devices like Jabra / Logitech,
as reported, too.

ARM: pxa: remove use of symbol_get()
commit 0faa29c4207e6e29cfc81b427df60e326c37083a upstream.
The spitz board file uses the obscure symbol_get() function
to optionally call a function from sharpsl_pm.c if that is
built. However, the two files are always built together
these days, and have been for a long time, so this can
be changed to a normal function call.

erofs: ensure that the post-EOF tails are all zeroed
commit e4c1cf523d820730a86cae2c6d55924833b6f7ac upstream.
This was accidentally fixed up in commit e4c1cf523d82 but we can't
take the full change due to other dependancy issues, so here is just
the actual bugfix that is needed.
[Background]
keltargw reported an issue [1] that with mmaped I/Os, sometimes the
tail of the last page (after file ends) is not filled with zeroes.
The root cause is that such tail page could be wrongly selected for
inplace I/Os so the zeroed part will then be filled with compressed
data instead of zeroes.
A simple fix is to avoid doing inplace I/Os for such tail parts,
actually that was already fixed upstream in commit e4c1cf523d82
("erofs: tidy up z_erofs_do_read_page()") by accident.

mmc: au1xmmc: force non-modular build and remove symbol_get usage
commit d4a5c59a955bba96b273ec1a5885bada24c56979 upstream.
au1xmmc is split somewhat awkwardly into the main mmc subsystem driver,
and callbacks in platform_data that sit under arch/mips/ and are
always built in. The latter than call mmc_detect_change through
symbol_get. Remove the use of symbol_get by requiring the driver
to be built in. In the future the interrupt handlers for card
insert/eject detection should probably be moved into the main driver,
and which point it can be built modular again.

modules: only allow symbol_get of EXPORT_SYMBOL_GPL modules
commit 9011e49d54dcc7653ebb8a1e05b5badb5ecfa9f9 upstream.
It has recently come to my attention that nvidia is circumventing the
protection added in 262e6ae7081d ("modules: inherit
TAINT_PROPRIETARY_MODULE") by importing exports from their proprietary
modules into an allegedly GPL licensed module and then rexporting them.
Given that symbol_get was only ever intended for tightly cooperating
modules using very internal symbols it is logical to restrict it to
being used on EXPORT_SYMBOL_GPL and prevent nvidia from costly DMCA
Circumvention of Access Controls law suites.
All symbols except for four used through symbol_get were already exported
as EXPORT_SYMBOL_GPL, and the remaining four ones were switched over in
the preparation patches.

nilfs2: fix general protection fault in nilfs_lookup_dirty_data_buffers()
commit f83913f8c5b882a312e72b7669762f8a5c9385e4 upstream.
A syzbot stress test reported that create_empty_buffers() called from
nilfs_lookup_dirty_data_buffers() can cause a general protection fault.
Analysis using its reproducer revealed that the back reference "mapping"
from a page/folio has been changed to NULL after dirty page/folio gang
lookup in nilfs_lookup_dirty_data_buffers().
Fix this issue by excluding pages/folios from being collected if, after
acquiring a lock on each page/folio, its back reference "mapping" differs
from the pointer to the address space struct that held the page/folio.

nilfs2: fix WARNING in mark_buffer_dirty due to discarded buffer reuse
commit cdaac8e7e5a059f9b5e816cda257f08d0abffacd upstream.
A syzbot stress test using a corrupted disk image reported that
mark_buffer_dirty() called from __nilfs_mark_inode_dirty() or
nilfs_palloc_commit_alloc_entry() may output a kernel warning, and can
panic if the kernel is booted with panic_on_warn.
This is because nilfs2 keeps buffer pointers in local structures for some
metadata and reuses them, but such buffers may be forcibly discarded by
nilfs_clear_dirty_page() in some critical situations.
This issue is reported to appear after commit 28a65b49eb53 ("nilfs2: do
not write dirty data after degenerating to read-only"), but the issue has
potentially existed before.
Fix this issue by checking the uptodate flag when attempting to reuse an
internally held buffer, and reloading the metadata instead of reusing the
buffer if the flag was lost.

serial: sc16is7xx: fix broken port 0 uart init
commit 2861ed4d6e6d1a2c9de9bf5b0abd996c2dc673d0 upstream.
The sc16is7xx_config_rs485() function is called only for the second
port (index 1, channel B), causing initialization problems for the
first port.
For the sc16is7xx driver, port->membase and port->mapbase are not set,
and their default values are 0. And we set port->iobase to the device
index. This means that when the first device is registered using the
uart_add_one_port() function, the following values will be in the port
structure:
port->membase = 0
port->mapbase = 0
port->iobase = 0
Therefore, the function uart_configure_port() in serial_core.c will
exit early because of the following check:
/*
* If there isn't a port here, don't do anything further.
*/
if (!port->iobase && !port->mapbase && !port->membase)
return;
Typically, I2C and SPI drivers do not set port->membase and
port->mapbase.
The max310x driver sets port->membase to ~0 (all ones). By
implementing the same change in this driver, uart_configure_port() is
now correctly executed for all ports.

serial: sc16is7xx: fix bug when first setting GPIO direction
commit 9baeea723c0fb9c3ba9a336369f758ed9bc6831d upstream.
When configuring a pin as an output pin with a value of logic 0, we
end up as having a value of logic 1 on the output pin. Setting a
logic 0 a second time (or more) after that will correctly output a
logic 0 on the output pin.
By default, all GPIO pins are configured as inputs. When we enter
sc16is7xx_gpio_direction_output() for the first time, we first set the
desired value in IOSTATE, and then we configure the pin as an output.
The datasheet states that writing to IOSTATE register will trigger a
transfer of the value to the I/O pin configured as output, so if the
pin is configured as an input, nothing will be transferred.
Therefore, set the direction first in IODIR, and then set the desired
value in IOSTATE.
This is what is done in NXP application note AN10587.

commit 1422b526fba994cf05fd288a152106563b875fce upstream.
In probe function, request_firmware_nowait() is called to load firmware
asynchronously. At completion of firmware loading, register_netdev() is
called. However, a mutex needed by netdev is initialized after the call
to request_firmware_nowait(). Consequently, it can happen that
register_netdev() is called before the driver is ready.
Move the mutex initialization into r8712_init_drv_sw(), which is called
before request_firmware_nowait().

tcpm: Avoid soft reset when partner does not support get_status
commit 78e0ea4277546debf7e96797ac3b768539cc44f6 upstream.
When partner does not support get_status message, tcpm right now
responds with soft reset message. This causes PD renegotiation to
happen and resets PPS link. Avoid soft resetting the link when
partner does not support get_status message to mitigate PPS resets.

usb: chipidea: imx: improve logic if samsung,picophy-* parameter is 0
commit 36668515d56bf73f06765c71e08c8f7465f1e5c4 upstream.
In current driver, the value of tuning parameter will not take effect
if samsung,picophy-* is assigned as 0. Because 0 is also a valid value
acccording to the description of USB_PHY_CFG1 register, this will improve
the logic to let it work.

usb: typec: tcpci: clear the fault status bit
commit 23e60c8daf5ec2ab1b731310761b668745fcf6ed upstream.
According the "USB Type-C Port Controller Interface Specification v2.0"
the TCPC sets the fault status register bit-7
(AllRegistersResetToDefault) once the registers have been reset to
their default values.
This triggers an alert(-irq) on PTN5110 devices albeit we do mask the
fault-irq, which may cause a kernel hang. Fix this generically by writing
a one to the corresponding bit-7.

USB PD controllers which consisting of a microcontroller (acting as the TCPM)
and a port controller (TCPC) - may require that the driver for the PD
controller accesses directly also the on-chip port controller in some cases.
Move tcpci.h to include/linux/usb/ is convenience access TCPC registers.
