From ba2d35c14b6fc554547cf647bedb71cd9ead3cab Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Mon, 17 Mar 2014 09:54:23 -0300 Subject: [PATCH] [media] v4l2-ioctl.c: fix sparse __user-related warnings Fix the use of __user in the check_array_args() prototype: instead of using 'void * __user *' you should use 'void __user **' for sparse to understand this correctly. This also required the use of __force in the '*kernel_ptr = user_ptr' assignment. Also replace a wrong cast (void *) with the correct one (void **) in check_array_args(). This fixes these sparse warnings: drivers/media/v4l2-core/v4l2-ioctl.c:2284:35: warning: incorrect type in assignment (different address spaces) drivers/media/v4l2-core/v4l2-ioctl.c:2301:35: warning: incorrect type in assignment (different address spaces) drivers/media/v4l2-core/v4l2-ioctl.c:2319:35: warning: incorrect type in assignment (different address spaces) drivers/media/v4l2-core/v4l2-ioctl.c:2386:57: warning: incorrect type in argument 4 (different address spaces) drivers/media/v4l2-core/v4l2-ioctl.c:2420:29: warning: incorrect type in assignment (different address spaces) Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab --- Reading git-format-patch failed
