From: Hans Verkuil <hans.verkuil@xxxxxxxxx>
Fix this warning:
drivers/media/v4l2-core/videobuf2-vmalloc.c:98:28: warning: incorrect type in assignment (different address spaces)
drivers/media/v4l2-core/videobuf2-vmalloc.c:158:28: warning: incorrect type in argument 1 (different address spaces)
The warning is correct, but we have no other choice here to forcibly cast.
At least it is now explicit that such a cast is needed.
