media: mc-device.c: don't memset __user pointer contents
You can't memset the contents of a __user pointer. Instead, call copy_to_user to copy links.reserved (which is zeroed) to the user memory. This fixes this sparse warning: SPARSE:drivers/media/mc/mc-device.c drivers/media/mc/mc-device.c:521:16: warning: incorrect type in argument 1 (different address spaces) Fixes: f4930887 ("media: media_device_enum_links32: clean a reserved field") Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Reviewed-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
