This bug is awaiting verification that the linux-oem-6.11/6.11.0-1014.14
kernel in -proposed solves the problem. Please test the kernel and
update this bug with the results. If the problem is solved, change the
tag 'verification-needed-noble-linux-oem-6.11' to 'verification-done-
noble-linux-oem-6.11'. If the problem still exists, change the tag
'verification-needed-noble-linux-oem-6.11' to 'verification-failed-
noble-linux-oem-6.11'.


If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.


See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Bug description:
  [Impact]
  When doing suspend test, the system will fail to be suspended since the 
MT7925 controller couldn't be suspended. The root cause is caused by the 
command timeout issued from mt7925 driver.

  [Fix]
  Cherry-pick the following two patches from linux-next:

  1b97fc8443ae wifi: mt76: mt7925: fix the unfinished command of regd_notifier 
before suspend
  8f6571ad470f wifi: mt76: mt7925: add handler to hif suspend/resume event

  Also, cherry-pick the following commits from linux-firmware:

  47c8a6053c64 linux-firmware: update firmware for MT7925 WiFi device
  62ee1c4b2d35 linux-firmware: update firmware for MT7925 WiFi device

  [Test Plan]
  1. Install Ubuntu image and boot into the OS
  2. Run the suspend test by $ fwts s3 --s3-device-check 
--s3-device-check-delay=60 --s3-multiple=1 --s3-sleep-delay=60, and see if the 
error occurred.

  [Where problems could occur]
  Due to the new FW, there might be a unexpected behavior of the MT7925 
hardware.
