12 * 5/24/00 Removed optional (and unnecessary) locking of the driver while

939 * First of all, this is non-interlaced stream, meaning that all scan lines
940 * are present in the datastream. There are 96 consecutive blocks of data
941 * that describe all 96 lines of the image. Each block is 5*128 bytes long
942 * and carries R, G, B components. The format of the block is shown in the
943 * code below. First 128*2 bytes are interleaved R and G components. Then
944 * we have a gap (junk data) 64 bytes long. Then follow B and something
945 * else, also interleaved (this makes another 128*2 bytes). After that
946 * probably another 64 bytes of junk follow.

833 * are closed. After that driver should be removable.

835 * This code handles surprise removal. The uvd->user is a counter which

837 * this counter is not 0 then we have a client who still has us opened.
838 * We set uvd->remove_pending flag as early as possible, and after that
839 * all access to the camera will gracefully fail. These failures should
840 * prompt client to (eventually) close the video device, and then - in
841 * usbvideo_v4l_close() - we decrement uvd->uvd_used and usage counter.
842 *
843 * History:
844 * 22-Jan-2000 Added polling of MOD_IN_USE to delay removal until all users gone.
845 * 27-Jan-2000 Reworked to allow pending disconnects; see xxx_close()
846 * 24-May-2000 Corrected to prevent race condition (MOD_xxx_USE_COUNT).
