When building video warnings pops up unused variable 'mdev',
drivers/staging/most/video/video.c: In function ‘vidioc_enum_fmt_vid_cap’:
drivers/staging/most/video/video.c:265:25: warning: unused variable ‘mdev’ [-Wunused-variable]
  struct most_video_dev *mdev = fh->mdev;
                         ^~~~
drivers/staging/most/video/video.c: In function ‘vidioc_g_fmt_vid_cap’:
drivers/staging/most/video/video.c:282:25: warning: unused variable ‘mdev’ [-Wunused-variable]
  struct most_video_dev *mdev = fh->mdev;
                         ^~~~
drivers/staging/most/video/video.c: In function ‘vidioc_g_std’:
drivers/staging/most/video/video.c:309:25: warning: unused variable ‘mdev’ [-Wunused-variable]
  struct most_video_dev *mdev = fh->mdev;
                         ^~~~

Remove the 'mdev' declaration.
