Subject[PATCH 16/17] x86/microcode/AMD: Issue microcode updated message later
Date
From: Borislav Petkov <bp@suse.de>

Before this, we issued this message from save_microcode_in_initrd()
which is called from free_initrd_mem(), i.e., only when we have an
initrd enabled. However, we can update from builtin microcode too but
then we don't issue the update message.

Fix it by issuing that message on the generic driver init path.
