Bug description:
[SRU Justification]
[Impact]
Sometimes MT7921 may not be probed due to an endless mcu reset:
[ 5.789548] mt7921 mcu reset 0
[ 5.790625] mt7921 rx type 0x7
[ 5.790625] mt7921 eid 0x1 ext_eid 0x0
[ 5.790626] mt76_rx_event eid 0x1 ext_eid 0x0
[Fix]
WiFi and Bluetooth firmware updates from mainline:
* e5a80ef8 linux-firmware: update frimware for mediatek bluetooth chip
(MT7921)
* d34196f5 linux-firmware: update firmware for MT7921 WiFi device
[Test Case]
This should fix the mcu reset and wireless/bluetooh devices should be
probed successfully.
[Where problems could occur]
While there is explicit FW API for kernel version compatibility checking,
this might introduce some hidden glitches that we don't know yet.
[Other Info]
MT7921 is supported since Impish 5.13 kernel, and Impish already has the
latest Bluetooth firmware, so only the WiFi one is proposed. For oem-5.13
and oem-5.14 in Focal, both firmware updates for Bluetooth and WiFi are
required.
========== original bug report ==========
[Reproduce Steps]
1.Add the wireless card MT7921 to SUT,Install the Ubuntu OS.
2.During OOBE, Open the settings, there is no wireless settings in the
panel,and the wifi cannot be used,issue occurred.
[Results]
Expected Result:The wireless settings should be exists and wifi can be used
Actual Result:The wireless settings not exists and wifi can not be used
