Subject: [PATCH] drm/i915/gvt: Fix error handling bug in perform_bb_shadow
Date: Sun, 15 Oct 2017 23:17:55 +0100 [thread overview]
Message-ID: <1508105875-14425-1-git-send-email-chris.gekas@gmail.com> (raw)
Change the type of variable 'bb_size' from uint32_t to int to be able to
hold error return values from find_bb_size(). This change seems to have
been missed from previous commit 1e3197d6ad73.
