From 7c424dd14fcf4c2905778ecd3f1ad10c5a097b5b Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Sat, 13 Dec 2014 08:52:54 -0300 Subject: [PATCH] [media] videobuf2-vmalloc: fix sparse warning 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.
