x86/microcode/amd: Tone down printk(), don't treat a missing firmware file as an error
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 Signed-off-by: Thomas Renninger <trenn@suse.de> Acked-by: Borislav Petkov <bp@suse.de> Link: http://lkml.kernel.org/r/1384274383-43510-1-git-send-email-trenn@suse.de Signed-off-by: Ingo Molnar <mingo@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
