Subject: [PATCH AUTOSEL 4.4 099/174] media: vivid: fix incorrect assignment operation when setting video mode
Date: Thu, 16 Jan 2020 12:41:36 -0500
Message-ID: <20200116174251.24326-99-sashal@kernel.org> (raw)
In-Reply-To: <20200116174251.24326-1-sashal@kernel.org>
From: Colin Ian King <colin.king@canonical.com>
[ Upstream commit d4ec9550e4b2d2e357a46fdc65d8ef3d4d15984c ]
The assigment of FB_VMODE_NONINTERLACE to var->vmode should be a
bit-wise or of FB_VMODE_NONINTERLACE instead of an assignment,
otherwise the previous clearing of the FB_VMODE_MASK bits of
var->vmode makes no sense and is redundant.
Addresses-Coverity: ("Unused value")
Fixes: ad4e02d5081d ("[media] vivid: add a simple framebuffer device for overlay testing")
