From 698f99ed5e06946764c3be035ce9d62a2691e08c Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Thu, 29 Apr 2021 12:53:27 +0300 Subject: [PATCH] vfio/mdev: remove unnecessary NULL check in mbochs_create() Originally "type" could be NULL and these checks were required, but we recently changed how "type" is assigned and that's no longer the case. Now "type" points to an element in the middle of a non-NULL array. Removing the checks does not affect runtime at all, but it makes the code a little bit simpler to read.
