Subject: drm/atomic: Add TV subconnector property to get/set_property
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=941731a2684251e8854366c75df19185f586c784;p=linux.git

drm/atomic: Add TV subconnector property to get/set_property

The subconnector property was created by drm_mode_create_tv_properties(),
but wasn't exposed to the userspace through the generic
atomic_get/set_property implementation, and wasn't stored in any generic
state structure.

Let's solve this.
