This bug is awaiting verification that the linux-oem-6.11/6.11.0-1018.18
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:
  ======================= Firmware ================

  [Impact]
  The new device needs a new firmware, rtw89/rtw8852bt_fw.bin.

  [Fix]
  Clear cherry picked the following commit from linux-firmware
  0a69dcd3 rtw89: 8852bt: update fw to v0.29.122.0 and BB parameter to 07
  882976ea rtw89: 8852bt: update fw to v0.29.110.0
  bb88fb74 rtw89: 8852bt: add firmware 0.29.91.0

  [Test]
  1. Boot up a system that comes with Realtek wifi device[10ec:b520]
  2. Check if the realtek wifi works

  [Where problems could occur]
  Adding one new firmware for the new device, there should be no regression.

  ======================= Kernel ================
