Subject: [media] media: Init the reserved fields of struct media_link_desc
|
|
|
|
struct media_link_desc is copy_to_user'ed as the return value of
|
|
MEDIA_IOC_ENUM_LINKS. When copying, the driver is omitting to initialise
|
|
the reserved fields. This commit fixes that by initialising the
|
|
reserved fields to 0.
