commit 6aade587d329ebe88319dfdb8e8c7b6aede80417 upstream.
In case when psp_init_asd_microcode() fails to load ASD microcode file, psp_v12_0_init_microcode() tries to print the firmware filename that failed to load before bailing out.
This is wrong because:
- the firmware filename it would want it print is an incorrect one as psp_init_asd_microcode() and psp_v12_0_init_microcode() are loading different filenames - it tries to print fw_name, but that's not yet been initialized by that time, so it prints random stack contents, e.g.
amdgpu 0000:04:00.0: Direct firmware load for amdgpu/renoir_asd.bin failed with error -2 amdgpu 0000:04:00.0: amdgpu: fail to initialize asd microcode amdgpu 0000:04:00.0: amdgpu: psp v12.0: Failed to load firmware "\xfeTO\x8e\xff\xff"
Fix that by bailing out immediately, instead of priting the bogus error message.
