Some devices, such as the Lenovo Yoga Tab 3 Pro (YT3-X90F) have
multiple batteries with a separate bq25890 charger for each battery.
This requires the bq25890_charger code to use a unique name per
registered power_supply class device, rather then hardcoding
"bq25890-charger" as power_supply class device name.
Add a "-%d" prefix to the name, allocated through idr in the same way
as several other power_supply drivers are already doing this.
Note this also updates: drivers/platform/x86/x86-android-tablets.c
which refers to the charger by power_supply-class-device-name for
the purpose of setting the "supplied-from" property on the fuel-gauge
to this name.

The recent "power: supply: bq25890: Add HiZ mode support" change
leaves F_CONV_RATE rate unset when disabling HiZ mode (setting
POWER_SUPPLY_PROP_ONLINE to 1) while a charger is connected.
Separate the resetting HiZ mode (when necessary because of a charger
(re)plug event) into its own "if {}" block which runs first.
And fix the setting of F_CONV_RATE rate by adding helper variables for
the old and new F_CONV_RATE state which check both the online and hiz bits
and then compare the helper variables to see if a F_CONV_RATE update is
necessary.

The bq25890 is capable of disconnecting itself from the external supply,
in which case the system is supplied only from the battery. This can be
useful e.g. to test the pure battery operation, or draw no power from
USB port.
Implement support for this mode, which can be toggled by writing 0 or
non-zero to sysfs 'online' attribute, to select either offline or online
mode.
The IRQ handler has to be triggered to update chip state, as switching
to and from HiZ mode does not generate an interrupt automatically.
The IRQ handler reinstates the HiZ mode in case a cable is replugged by
the user, the chip itself clears the HiZ mode bit when cable is plugged
in by the user and the chip detects PG bad-to-good transition.

A call to platform_get_irq_byname() already prints an error on failure
within its own implementation. So printing another error based on its

clean up also makes if condition block braces and the device pointer

Since filemap_update_page() calls filemap_read_folio() after calling

If v4 READDIR operation hits a mountpoint and gets back an error,
then it will include that entry in the reply and set RDATTR_ERROR for it
to the error.
That's fine for "normal" exported filesystems, but on the v4root, we
need to be more careful to only expose the existence of dentries that
lead to exports.
If the mountd upcall times out while checking to see whether a
mountpoint on the v4root is exported, then we have no recourse other
than to fail the whole operation.

This also caused overlay plane width to be rounded up, which was not
intended. Fix overlay plane width by limiting the rounding up to the
primary plane.

[ 9.444502] matroxfb: cannot determine memory size
[ 9.449316] matroxfb: probe of 0000:0a:03.0 failed with error -1
So, add the missing 0 to make it the intended 16 MB. Successfully tested on
the Dell PowerEdge R910/0KYD3D, BIOS 2.10.0 08/29/2013, that the warning is
gone.
While at it, add a leading 0 to the maxdisplayable entry, so it’s aligned
properly. The value could probably also be increased from 8 MB to 16 MB, as
the G200 uses the same values, but I have not checked any datasheet.
Note, matroxfb is obsolete and superseded by the maintained DRM driver
mga200, which is used by default on most systems where both drivers are
available. Therefore, on most systems it was only a cosmetic issue.

The drm_sched_entity_kill() is invoked twice by drm_sched_entity_destroy()
while userspace process is exiting or being killed. First time it's invoked
when sched entity is flushed and second time when entity is released. This
causes a lockup within wait_for_completion(entity_idle) due to how completion
API works.
Calling wait_for_completion() more times than complete() was invoked is a
error condition that causes lockup because completion internally uses
counter for complete/wait calls. The complete_all() must be used instead
in such cases.
This patch fixes lockup of Panfrost driver that is reproducible by killing
any application in a middle of 3d drawing operation.

When adding/deleting large number of elements in one step in ipset, it can
take a reasonable amount of time and can result in soft lockup errors. The
patch 5f7b51bf09 ("netfilter: ipset: Limit the maximal range of
consecutive elements to add/delete") tried to fix it by limiting the max
elements to process at all. However it was not enough, it is still possible
that we get hung tasks. Lowering the limit is not reasonable, so the
approach in this patch is as follows: rely on the method used at resizing
sets and save the state when we reach a smaller internal batch limit,
unlock/lock and proceed from the saved state. Thus we can avoid long
continuous tasks and at the same time removed the limit to add/delete large
number of elements in one step.
The nfnl mutex is held during the whole operation which prevents one to
issue other ipset commands in parallel.

Add more coverage to our standard test cases:
- 8kHz mono and stereo to verify that the most common mono format is
clocked correctly.
- 44.1kHz stereo to verify that this different clock base is generated
accurately.
- 48kHz 6 channel to verify that 6 channel is clocked correctly.
- 96kHz stereo since that is a common audiophile rate.

In order to help with the comprehensibility of tests it is useful for us to
document what the test is attempting to cover. We could just do this through
comments in the configuration files but in order to aid people looking at
the output of the program in logs let's provide support for an optional
'description' directive which we log prior to running each of the tests.

Since we don't know what the capabilities of an unknown card is any of our
standard tests may fail due to not being supported by the system. Set a
flag once we've configured the stream, just before we start data, to say
that the system accepted our stream configuration.
Since there shouldn't be a use case for tests that are specified for the
individual system failing for those tests we also add a new test which
fails if we are unable to configure the settings specified in the system
specific configuration file.

Rather than allowing the system specific tests to replace the default set
of tests instead run them in addition to the standard set of tests. In
order to avoid name collisions in the reported tests we add an additional
test class element to the reported tests. Doing this means we always get a
consistent baseline of coverage no matter what card we run on but retain
the ability to specify specific coverage for a given system.

may be variable per specific hardware.
Also, handle alt_formats field now (with the fixes in the format loop).
It replaces the original "automatic" logic which is not so universal.

There is an issue with the checking of the return value of
'of_get_mac_address', which returns 0 on success and negative value on
failure. The driver interpretated the result the opposite way. Therefore
if there was a MAC address defined in the DT, then the driver was
generating a random MAC address otherwise it would use address 0.
Fix this by checking correctly the return value of 'of_get_mac_address'
