Subject: media: media-device.c: zero reserved fields
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=fcab757396b29b72e76c66d0216c923094ff69fc;p=openwrt%2Fstaging%2Fblogic.git

media: media-device.c: zero reserved fields

MEDIA_IOC_SETUP_LINK didn't zero the reserved field of the media_link_desc
struct. Do so in media_device_setup_link().

MEDIA_IOC_ENUM_LINKS didn't zero the reserved field of the media_links_enum
struct. Do so in media_device_enum_links().
