Public bug reported:
[SRU Justifications]
========== linux-firmware ==========
[Impact]
The kernel log shows missing files while bringing up audio drivers. It won't
affect basic audio functions but could impact the mechanisms or handles with
the Soundwire MIPI function.
[Fix]
It required the realtek/rt1320/rt1320-patch-code-vc.bin in linux-firmware
[Test Case]
1. Boot up the machine with Realtek Audio RT722+RT1320 (Dell GhostRider
platform)
2. Make sure the rt1320-patch-code-vc.bin is in /lib/firmware/realtek/rt1320
3. After boot, check the kernel log by `dmesg` and there should be no firmware
load error message as follows
rt1320-sdca sdw:0:2:025d:1320:01: Direct firmware load for
realtek/rt1320/rt1320-patch-code-vc.bin failed with error -2
rt1320-sdca sdw:0:2:025d:1320:01: rt1320_load_mcu_patch: Failed to load
realtek/rt1320/rt1320-patch-code-vc.bin firmware
[Where problems could occur]
It won't affect the audio basic function and only loaded on platforms with
Realtek rt1320 amplifier. No risk for regression
