Pull char/misc driver fixes for real from Greg KH:
 "Let's tag the proper branch this time...

  Here are some small char/misc driver fixes for 5.19-rc3 that resolve
  some reported issues.

  They include:

   - mei driver fixes

   - comedi driver fix

   - rtsx build warning fix

   - fsl-mc-bus driver fix

  All of these have been in linux-next for a while with no reported
  issues"

This is what the merge in commit f0ec9c65a8d6 _should_ have merged, but
Greg fat-fingered the pull request and I got some small changes from
linux-next instead there. Credit to Nathan Chancellor for eagle-eyes.

Drop HBM responses also in the early shutdown phase where
the usual traffic is allowed.
Extend the rule that drop HBM responses received during the shutdown
phase by also in MEI_DEV_POWERING_DOWN state.
This resolves the stall if the driver is stopping in the middle
of the link initialization or link reset.

Drop the capabilities response on early shutdown.

Link reset flow is always performed in the runtime resumed state.
The internal PG state may be left as ON after the suspend
and will not be updated upon the resume if the D0i3 is not supported.

Ensure that the internal PG state is set to the right value on the flow
entrance in case the firmware does not support D0i3.

platform_get_irq() returns negative error number instead 0 on failure.
And the doc of platform_get_irq() provides a usage example:

    int irq = platform_get_irq(pdev, 0);
    if (irq &lt; 0)
        return irq;

Fix the check of return value to catch errors correctly.

Clang warns:

  drivers/misc/cardreader/rts5261.c:406:13: error: variable 'setting_reg2' is used uninitialized whenever 'if' condition is false [-Werror,-Wsometimes-uninitialized]
          } else if (efuse_valid == 0) {

efuse_valid == 1 is not a valid value so just return early from the

Pull char / misc / other smaller driver subsystem updates from Greg KH:
 "Here is the large set of char, misc, and other driver subsystem
  updates for 5.19-rc1. The merge request for this has been delayed as I
  wanted to get lots of linux-next testing due to some late arrivals of
  changes for the habannalabs driver.

  Highlights of this merge are:

   - habanalabs driver updates for new hardware types and fixes and
     other updates

   - IIO driver tree merge which includes loads of new IIO drivers and
     cleanups and additions

   - PHY driver tree merge with new drivers and small updates to
     existing ones

   - interconnect driver tree merge with fixes and updates

   - soundwire driver tree merge with some small fixes

   - coresight driver tree merge with small fixes and updates

   - mhi bus driver tree merge with lots of updates and new device
     support

   - firmware driver updates

   - fpga driver updates

   - lkdtm driver updates (with a merge conflict, more on that below)

   - extcon driver tree merge with small updates

   - lots of other tiny driver updates and fixes and cleanups, full
     details in the shortlog.

  All of these have been in linux-next for almost 2 weeks with no
  reported problems"

Pull USB / Thunderbolt updates from Greg KH:
 "Here is the "big" set of USB and Thunderbolt driver changes for
  5.18-rc1. For the most part it's been a quiet development cycle for
  the USB core, but there are the usual "hot spots" of development
  activity.

  Included in here are:

   - Thunderbolt driver updates:
       - fixes for devices without displayport adapters
       - lane bonding support and improvements
       - other minor changes based on device testing

   - dwc3 gadget driver changes.

     It seems this driver will never be finished given that the IP core
     is showing up in zillions of new devices and each implementation
     decides to do something different with it...

   - uvc gadget driver updates as more devices start to use and rely on
     this hardware as well

   - usb_maxpacket() api changes to remove an unneeded and unused
     parameter.

   - usb-serial driver device id updates and small cleanups

   - typec cleanups and fixes based on device testing

   - device tree updates for usb properties

   - lots of other small fixes and driver updates.

  All of these have been in linux-next for weeks with no reported
  problems"
