Subject: [PATCH][next] drm/i915: remove redundant checks for a null fb pointer
Date: Tue, 10 Dec 2019 14:23:49 +0000	[thread overview]
Message-ID: <20191210142349.333171-1-colin.king@canonical.com> (raw)

From: Colin Ian King <colin.king@canonical.com>

A prior check and return when pointer fb is null makes
subsequent null checks on fb redundant.  Remove the redundant
null checks.

Addresses-Coverity: ("Logically dead code")
