From mboxrd@z Thu Jan 1 00:00:00 1970 From: Colin King Date: Wed, 15 Mar 2017 17:10:10 +0000 Subject: [PATCH] x86/microcode/AMD: remove redundant null check on mc Message-Id: <20170315171010.17536-1-colin.king@canonical.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: Borislav Petkov , Thomas Gleixner , Ingo Molnar , "H . Peter Anvin" , x86@kernel.org Cc: kernel-janitors@vger.kernel.org, linux-kernel@vger.kernel.org From: Colin Ian King mc is a pointer to the static u8 array amd_ucode_patch and therefore can never be null, so the check is redundant. Remove it.
