possible warning fix

The warning in the log is harmless, but this patch should fix it.

Problem in firmware. I downgrade linux-firmware package, pp_dpm_mclk now "0: 400Mhz" at start.
Comment 8 Alex Deucher 2020-12-07 19:25:25 UTC 
Can you narrow down which specific firmware?  Also what what versions did you try?

workly: linux-firmware 20201023.dae4b4c-1
All new versions is bugged. Cant do build per single commits (expensive traffic).

Comment 11 cpl 2020-12-22 06:29:16 UTC 
Same issue on Vega 6, this is also causing worse gpu performance. Reverting this commit fixes it: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/?id=3bcc4c1df91f879fb4f01a6b48a9c12fc7b6e724

That said, memory clock is now stuck on 933Mhz. (Performance is good, though.)
Comment 12 Jothi Prasath 2024-05-14 18:35:14 UTC 
I face this same issue.
I am using ryzen 5 5500u with vega7 
kernel version: 6.8.9

cat /sys/class/drm/card1/device/pp_dpm_mclk
0: 400Mhz
1: 800Mhz
2: 1200Mhz *
3: 1333Mhz

the mclk is always sticking to 1200Mhz
