Subject: [PATCH] drm/i915/guc: remove redundant GEM_BUG_ON check
Date: Mon, 11 Jun 2018 17:00:37 +0100 [thread overview]
Message-ID: <20180611160037.23402-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
The check for level being less than zero is redundant as level
is an unsigned u32 and hence will never be less than zero.
Remove this redundant check.
Detected by CoverityScan, CID#1468363 ("Macro compares unsigned to 0")
Signed-off-by: Colin Ian King <colin.king@canonical.com>
