[media] videobuf2: Fix vb2_write prototype
struct v4_file_operations defines the data param as const char __user *data but on vb2 is defined as char __user *data. This patch fixes the warnings produced by this. ie: drivers/qtec/qtec_xform.c:817:2: warning: initialization from incompatible pointer type [enabled by default] drivers/qtec/qtec_xform.c:817:2: warning: (near initialization for ‘qtec_xform_v4l_fops.write’) [enabled by default] Signed-off-by: Ricardo Ribalda Delgado <ricardo.ribalda@gmail.com> Acked-by: Marek Szyprowski <m.szyprowski@samsung.com> Signed-off-by: Sylwester Nawrocki <s.nawrocki@samsung.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
