Subject: [patch] i915: signedness bug in check_overlay_src()
Date: Wed, 27 Oct 2010 21:17:25 +0000 [thread overview]
Message-ID: <20101027211724.GI6062@bicker> (raw)
"depth" should be signed in case packed_depth_bytes() returns -EINVAL.
This probably doesn't make a difference at runtime. In the original
code we would return -EINVAL later if (rec->offset_Y % 4294967274) is
non-zero.
