3.5.7.27 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Thomas Renninger <trenn@suse.de>
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
