Subject: [PATCH 03/11] x86/ucode/amd: Don't use void * for microcode_patch->mpb
Date: Tue, 31 Mar 2020 11:05:23 +0100	[thread overview]
Message-ID: <20200331100531.4294-4-andrew.cooper3@citrix.com> (raw)
In-Reply-To: <20200331100531.4294-1-andrew.cooper3@citrix.com>

All code works fine with it having its correct type, and it even allows us to
drop two casts in a printk().

No functional change.
