[media] v4l: omap4iss: Replace udelay/msleep with usleep_range
The only udelay() call takes place in a sleepable context, we can sleep instead. Use usleep_range(). Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Acked-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
