   4 Subject: [PATCH 377/454] staging: bcm2835-camera: Fix warnings about string
   5  ops on v4l2 uapi.
   6
   7 commit 40b73e16675ee2e77358ed1cfc3364c8bf000e4f upstream.
   8
   9 The v4l2 uapi uses u8[] for strings, so cast those to char * to avoid
  10 compiler warnings about unsigned vs signed with sprintf() and friends.
