- regarding the LO switch patch. I've got info about that from two persons
independently hence not sure what tags to put there and who should be
the author. Please let me know if that needs to be corrected.
- the wcd937x pdm watchdog is a problem for audio playback and needs to be
fixed. The minimal fix would be to at least increase timeout value but
it will still trigger in case of plenty of dbg messages or other
delay-generating things. Unfortunately, I can't test HPHL/R outputs hence
the patch is only for AUX. The other options would be introducing
module parameter for debugging and using HOLD_OFF bit for that or
adding Kconfig option.

ASoC: codecs: wcd937x: relax the AUX PDM watchdog
On a system with wcd937x, rxmacro and Qualcomm audio DSP, which is pretty
common set of devices on Qualcomm platforms, and due to the order of how
DAPM widgets are powered on (they are sorted), there is a small time window
when wcd937x chip is online and expects the flow of incoming data but
rxmacro is not yet online. When wcd937x is programmed to receive data
via AUX port then its AUX PDM watchdog is enabled in
wcd937x_codec_enable_aux_pa(). If due to some reasons the rxmacro and
soundwire machinery are delayed to start streaming data, then there is
a chance for this AUX PDM watchdog to reset the wcd937x codec. Such event
is not logged as a message and only wcd937x IRQ counter is increased
however there could be a lot of other reasons for that IRQ.
There is a similar opportunity for such delay during DAPM widgets power
down sequence.
If wcd937x codec reset happens on the start of the playback, then there
will be no sound and if such reset happens at the end of a playback then
it may generate additional clicks and pops noises.
On qrb4210 RB2 board without any debugging bits the wcd937x resets are
sometimes observed at the end of a playback though not always.
With some debugging messages or with some tracing enabled the AUX PDM
watchdog resets the wcd937x codec at the start of a playback and there
is no sound output at all.
In this patch:
- TIMEOUT_SEL bit in PDM_WD_CTL2 register is set to increase the watchdog
reset delay to 100ms which eliminates the AUX PDM watchdog IRQs on
qrb4210 RB2 board completely and decreases the number of unwanted clicks
noises;
- HOLD_OFF bit postpones triggering such watchdog IRQ till wcd937x codec
reset which usually happens at the end of a playback. This allows to
actually output some sound in case of debugging.

the detected registers are CDC_RX_RX2_RX_PATH_SEC7 and
CDC_RX_RX2_RX_PATH_DSM_CTL.
CDC_RX_RXn_RX_PATH_DSM_CTL(rx, n) macro incorrectly generates the address

CDC_RX_RX2_RX_PATH_SEC7 which is located at 0x540.
The same goes for CDC_RX_RXn_RX_PATH_SEC7(rx, n).
Fix this by introducing additional rxn_reg_stride2 offset. For 2.5 version
and above this offset will be equal to 0.
With such change the corresponding RXn() macros will generate the same
values for 2.5 codec version for all RX paths and the same old values
for pre-2.5 version for RX0 and RX1. However for the latter case with
RX2 path it will also add rxn_reg_stride2 on top.

The reason for this error is physical_package_ids assigned by VMware VMM
are not continuous and have gaps. This will cause value returned by
topology_physical_package_id() to be more than topology_max_packages().
Here the allocation uses topology_max_packages(). The call to
topology_max_packages() returns maximum logical package ID not physical
ID. Hence use topology_logical_package_id() instead of
topology_physical_package_id().

It should have been deleted at the time of the LRU rework; since it

While reviewing the patch, Honza found that when adjusting resize_bg in
alloc_flex_gd(), it was possible for flex_gd->resize_bg to be bigger than
flexbg_size.
The reproduction of the problem requires the following:
ext4: mark fc as ineligible using an handle in ext4_xattr_set()
Calling ext4_fc_mark_ineligible() with a NULL handle is racy and may result
in a fast-commit being done before the filesystem is effectively marked as
ineligible. This patch moves the call to this function so that an handle
can be used. If a transaction fails to start, then there's not point in
trying to mark the filesystem as ineligible, and an error will eventually be
returned to user-space.
ext4: use handle to mark fc as ineligible in __track_dentry_update()
Calling ext4_fc_mark_ineligible() with a NULL handle is racy and may result
in a fast-commit being done before the filesystem is effectively marked as

__track_dentry_update() by adding an extra parameter to the callback used in
ext4_fc_track_template().

Pull tracing fixes from Steven Rostedt:
- Fix tp_printk command line option crashing the kernel
With the code that can handle a buffer from a previous boot, the
trace_check_vprintf() needed access to the delta of the address space
used by the old buffer and the current buffer. To do so, the
trace_array (tr) parameter was used. But when tp_printk is enabled on
the kernel command line, no trace buffer is used and the trace event
is sent directly to printk(). That meant the tr field of the iterator
descriptor was NULL, and since tp_printk still uses
trace_check_vprintf() it caused a NULL dereference.

Pull ACPI fixes from Rafael Wysocki:
"These fix up the ACPI IRQ override quirk list and add two new entries
to it, add a new quirk to the ACPI backlight (video) driver, and fix
the ACPI battery driver.
Specifics:
- Add a quirk for Dell OptiPlex 5480 AIO to the ACPI backlight
(video) driver (Hans de Goede)
- Prevent the ACPI battery driver from crashing when unregistering a
battery hook and simplify battery hook locking in it (Armin Wolf)
- Fix up the ACPI IRQ override quirk list and add quirks for Asus
Vivobook X1704VAP and Asus ExpertBook B2502CVA to it (Hans de
Goede)"
