Subject: [PATCH] drivers/media/video/zr364xx.c: add missing cleanup code

From: Julia Lawall <julia@...u.dk>

It seems just as necessary to free cam->vdev and cam in this error case as
in the next one.

Signed-off-by: Julia Lawall <julia@...u.dk>

There is yet another block of error handling code below the call to
zr364xx_board_init, but perhaps no cleanup code is needed in that case,
because that code is currently initializing a lock in cam?
