Subject: [PATCH AUTOSEL 3.18 09/19] fbdev: omapfb: off by one in omapfb_register_client()
Date: Fri, 7 Sep 2018 00:39:32 +0000 [thread overview]
Message-ID: <20180907003923.58019-9-alexander.levin@microsoft.com> (raw)
In-Reply-To: <20180907003923.58019-1-alexander.levin@microsoft.com>
From: Dan Carpenter <dan.carpenter@oracle.com>
[ Upstream commit 5ec1ec35b2979b59d0b33381e7c9aac17e159d16 ]
The omapfb_register_client[] array has OMAPFB_PLANE_NUM elements so the
> should be >= or we are one element beyond the end of the array.
Fixes: 8b08cf2b64f5 ("OMAP: add TI OMAP framebuffer driver")
