[PATCH] media: vivid: fix incorrect assignment operation when setting video mode

From: Colin King
Date: Tue Jun 04 2019 - 11:01:11 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

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")
