Subject: [PATCH] [media] cx25821: Fix compilation breakage due to BKL
 dependency
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

drivers/staging/cx25821/cx25821-video.c: In function ‘video_open’:
drivers/staging/cx25821/cx25821-video.c:817:8: error: implicit declaration of function ‘lock_kernel’
drivers/staging/cx25821/cx25821-video.c:834:9: error: implicit declaration of function ‘unlock_kernel’

This patch just adds a header with BKL function. It should be enough
to avoid compilation breakage, but, as BKL will be removed, we need
to properly fix it on a latter patch.
