Subject: x86/microcode/amd: Tone down printk(), don't treat a missing firmware file as an error
From: Thomas Renninger <trenn@xxxxxxx>
commit 11f918d3e2d3861b6931e97b3aa778e4984935aa upstream.
Do it the same way as done in microcode_intel.c: use pr_debug()
for missing firmware files.
There seem to be CPUs out there for which no microcode update
has been submitted to kernel-firmware repo yet resulting in
scary sounding error messages in dmesg:
microcode: failed to load file amd-ucode/microcode_amd_fam16h.bin
