Hi Sergei,

Thanks for your review, I have been sent v2 with the updated commit message:
https://lore.kernel.org/patchwork/patch/1242218/

Thanks,
Tiezhu Yang

instead of as a module, we should make sure the firmware for the model
(check available ones in /lib/firmware/radeon) is built-in to the kernel

as well, otherwise there exists the following fatal error during GPU init,

change CONFIG_DRM_RADEON=y to CONFIG_DRM_RADEON=m to fix it.
