There's no reason to proceed with applying workaround and initing
sysfs if we are going to abort the probe upon failure.

This patch updates the mlxbf_gige driver to support the
"get_pause_stats()" callback, which enables display of
pause frame counters via "ethtool -I -a oob_net0".
The pause frame counters are only enabled if the "counters_en"
bit is asserted in the LLU general config register. The driver
will only report stats, and thus overwrite the default stats
state of ETHTOOL_STAT_NOT_SET, if "counters_en" is asserted.

Kernel bot has discovered that if CONFIG_GPIOLIB is not set compilation
will fail.
Upon investigation the issue is that qca807x_gpio() is guarded by a
preprocessor check but then it is called under
if (IS_ENABLED(CONFIG_GPIOLIB)) in the probe call so the compiler will
error out since qca807x_gpio() has not been declared if CONFIG_GPIOLIB has
not been set.

Commit 3e2f544dd8a33 ("net: get stats64 if device if driver is
configured") moved the callback to dev_get_tstats64() to net core, so,
unless the driver is doing some custom stats collection, it does not
need to set .ndo_get_stats64.
Since this driver is now relying in NETDEV_PCPU_STAT_TSTATS, then, it
doesn't need to set the dev_get_tstats64() generic .ndo_get_stats64
function pointer.

With commit 34d21de99cea9 ("net: Move {l,t,d}stats allocation to core and
convert veth & vrf"), stats allocation could be done on net core
instead of in this driver.
With this new approach, the driver doesn't have to bother with error
handling (allocation failure checking, making sure free happens in the
right spot, etc). This is core responsibility now.
Remove the allocation in the geneve driver and leverage the network
core allocation instead.

There is no reason to use RESERVEDMEM_OF_DECLARE() as the initialization
hook just saves off the base address and size. Use of
RESERVEDMEM_OF_DECLARE() is reserved for non-driver code and
initialization which must be done early. For qbman, retrieving the
address and size can be done in probe just as easily.

The ATS2851 controller erroneously reports support for the "Read
Encryption Key Length" HCI command. This makes it unable to connect
to any devices, since this command is issued by the kernel during the
connection process in response to an "Encryption Change" HCI event.
Add a new quirk (HCI_QUIRK_BROKEN_ENC_KEY_SIZE) to hint that the command
is unsupported, preventing it from interrupting the connection process.
This is the error log from btmon before this patch:
> HCI Event: Encryption Change (0x08) plen 4

Since dracut refers to the module info for defining the required
firmware files and btmtk driver doesn't provide the firmware info for
MT7922, the generate initrd misses the firmware, resulting in the
broken Bluetooth.
This patch simply adds the MODULE_FIRMWARE() for the missing entry
for covering that.

The problem is detected by KASAN.
btrtl driver uses private hci data to store 'struct btrealtek_data'.
If btrtl driver is used with btusb, then memory for private hci data
is allocated in btusb. But no private data is allocated after hci_dev,
when btrtl is used with hci_h5.
This commit adds memory allocation for hci_h5 case.

The optional variants for the gpiod_get() family of functions return NULL
if the GPIO in question is not associated with this device. They return
ERR_PTR() on any other error. NULL descriptors are graciously handled by
GPIOLIB and can be safely passed to any of the GPIO consumer interfaces
as they will return 0 and act as if the function succeeded. If one is
using the optional variant, then there's no point in checking for NULL.

This fixes the tx timeout issue seen while running a stress test on
btnxpuart for couple of hours, such that the interval between two HCI
commands coincide with the power save timeout value of 2 seconds.
Test procedure using bash script:
<load btnxpuart.ko>
hciconfig hci0 up
//Enable Power Save feature
hcitool -i hci0 cmd 3f 23 02 00 00
while (true)
do
hciconfig hci0 leadv
sleep 2
hciconfig hci0 noleadv
sleep 2
done
Error log, after adding few more debug prints:
Bluetooth: btnxpuart_queue_skb(): 01 0A 20 01 00
Bluetooth: hci0: Set UART break: on, status=0
Bluetooth: hci0: btnxpuart_tx_wakeup() tx_work scheduled
Bluetooth: hci0: btnxpuart_tx_work() dequeue: 01 0A 20 01 00
Can't set advertise mode on hci0: Connection timed out (110)
Bluetooth: hci0: command 0x200a tx timeout
When the power save mechanism turns on UART break, and btnxpuart_tx_work()
is scheduled simultaneously, psdata->ps_state is read as PS_STATE_AWAKE,
which prevents the psdata->work from being scheduled, which is responsible
to turn OFF UART break.
This issue is fixed by adding a ps_lock mutex around UART break on/off as
well as around ps_state read/write.
btnxpuart_tx_wakeup() will now read updated ps_state value. If ps_state is
PS_STATE_SLEEP, it will first schedule psdata->work, and then it will
reschedule itself once UART break has been turned off and ps_state is
PS_STATE_AWAKE.
Tested above script for 50,000 iterations and TX timeout error was not
observed anymore.

Commit e7794c14fd73 ("mmc: rpmb: fixes pause retune on all RPMB
partitions.") added a mask check for 'part_type', but the mask used was
wrong leading to the code intended for rpmb also being executed for GP3.
On some MMCs (but not all) this would make gp3 partition inaccessible:
armadillo:~# head -c 1 < /dev/mmcblk2gp3
head: standard input: I/O error

the part_type values of interest here are defined as follow:

boot1 2
rpmb 3

gp2 6
gp3 7
so mask with EXT_CSD_PART_CONFIG_ACC_MASK (7) to correctly identify rpmb

Using the ring_muxer without preemption adds overhead for no
reason since mcbp cannot be triggered.
Moving back to a single queue in this case also helps when
high priority app are used: in this case the gpu_scheduler
priority handling will work as expected - much better than
ring_muxer with its 2 independant schedulers competing for
the same hardware queue.
This change requires moving amdgpu_device_set_mcbp above
amdgpu_device_ip_early_init because we use adev->gfx.mcbp.
