Subject: [PATCH] drm/mcde: Fix an uninitialized variable
Date: Wed, 29 May 2019 11:34:58 +0000 [thread overview]
Message-ID: <20190529113458.GG19119@mwanda> (raw)
We never set "vblank" to "false".
Current versions of GCC will initialize it to zero automatically at
certain optimization levels so that's probably why this didn't show up
in testing.
Fixes: 5fc537bfd000 ("drm/mcde: Add new driver for ST-Ericsson MCDE")
Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com>
