The DSDT for the Asus TF103C specifies a IOAPIC IRQ for the HCI -> host IRQ
but this is not correct. Unlike the previous entries in the table, this
time the correct GPIO to use instead is known; and the TF103C is battery
powered making runtime-pm support more important.
Extend the bcm_broken_irq_dmi_table mechanism to allow specifying the right
GPIO instead of just always disabling runtime-pm and add an entry to it for
the Asus TF103C.

Fix the following kernel oops in btmtksdio_interrrupt

[ 14.339168] kthread+0x148/0x3ac
[ 14.339176] ret_from_fork+0x10/0x30
That happened because hdev->power_on is already called before
sdio_set_drvdata which btmtksdio_interrupt handler relies on is not
properly set up.
The details are shown as the below: hci_register_dev would run
queue_work(hdev->req_workqueue, &hdev->power_on) as WQ_HIGHPRI
workqueue_struct to complete the power-on sequeunce and thus hci_power_on
may run before sdio_set_drvdata is done in btmtksdio_probe.
The hci_dev_do_open in hci_power_on would initialize the device and enable
the interrupt and thus it is possible that btmtksdio_interrupt is being
called right before sdio_set_drvdata is filled out.
When btmtksdio_interrupt is being called and sdio_set_drvdata is not filled
, the kernel oops is going to happen because btmtksdio_interrupt access an
uninitialized pointer.

Another subset of the more recent batch of Chinese clones aren't
specs-compliant and seem to lock up whenever they receive a
HCI_OP_SET_EVENT_FLT with flt_type set to zero/HCI_FLT_CLEAR_ALL,
which on Linux (until the recent HCI state-machine refactor) happened
right at BR/EDR setup. As there are other less-straightforward ways
of reaching those operations, this patch is still relevant.
So, while all the previous efforts to wrangle the herd of fake CSRs
seem to be paying off (and these also get detected as such) we
still need to take care of this quirk; testers seem to agree
that these dongles tend to work well enough afterwards.
From some cursory USB packet capture on Windows it seems like
that driver doesn't appear to use this clear-all functionality at all.
This patch was tested on some really popular AliExpress-style
dongles, in my case marked as "V5.0". Chip markings: UG8413,
the backside of the PCB says "USB Dangel" (sic).
Here is the `hciconfig -a` output; for completeness:

Also, changed the benign dmesg print that shows up whenever the

Add power reset for bluetooth via enable-gpios in h5_btrtl_open function.
While testing the RTL8822CS SDIO WiFi/BT adapter, it was found that in
some cases the kernel could not initialize BT firmware. However,
manually resetting the adapter via gpio (off/on sequence) allows it to
start correctly.
Apparently, when the system starts, the adapter is in an undefined state
(including unknown gpio state after starting uboot). A forced reset helps
to initialize the adapter in most cases. It has been found experimentally
that 100 ms is sufficient for a reset.

Currently, there is a loop in btmtksdio_txrx_work() which iteratively
executes until the variable int_status is zero.
But the variable int_status should be masked out with the actual interrupt
sources (MTK_REG_CHISR bit 0-15) before we check the loop condition.
Otherwise, RX_PKT_LEN (MTK_REG_CHISR bit 16-31) which is read-only and
unclearable would cause the loop to get stuck on some chipsets like
MT7663s.

vdpa: Add support for returning device configuration information
vdpa/mlx5: Support configuring max data virtqueue
vdpa/mlx5: Fix config_attr_mask assignment
vdpa: Allow to configure max data virtqueues
vdpa: Read device configuration only if FEATURES_OK
vdpa: Sync calls set/get config/status with cf_mutex

...
This will enable cleanups down the road.
The idea is to disable cbs, then add "flush_queued_cbs" callback
as a parameter, this way drivers can flush any work
queued after callbacks have been disabled.

Here is the big set of tty/serial driver updates for 5.17-rc1.
Nothing major in here, just lots of good updates and fixes, including:
- more tty core cleanups from Jiri as well as mxser driver
cleanups. This is the majority of the core diffstat
- tty documentation updates from Jiri
- platform_get_irq() updates
- various serial driver updates for new features and hardware
- fifo usage for 8250 console, reducing cpu load a lot
- LED fix for keyboards, long-time bugfix that went through many
revisions
- minor cleanups
All have been in linux-next for a while with no reported problems.

The driver has to issue the specific command to enable Bluetooth SCO over
the I2S/PCM interface on mt7921s, that is supported since the firmware
with version 20211222191101 was added, and the patch would not cause any
harm even when the old firmware is applied.
The SCO profile with the patch was tested by setting up a VOIP application,
connected to HFP device, checked telephony function can work normally.

Enable wake on bluetooth on mt7921s that can be supported since the
firmware with version 20211129211059 was added, and the patch would
not cause any harm even when the old firmware is applied.
The patch was tested by setting up an HID or HOGP profile to connect a
Bluetooth keyboard and mouse, then putting the system to suspend, then
trying to wake up the system by moving the Bluetooth keyboard or mouse,
and then checking if the system can wake up and be brought back to
the normal state.
