Subject: [PATCH] [media] Better define MEDIA_ENT_F_CONN_* entities
Date: Thu, 3 Mar 2016 10:31:02 -0300 [thread overview]
Message-ID: <32c88fe4e8378ec6a2d74f65f88b004cdd815d82.1457011857.git.mchehab@osg.samsung.com> (raw)
Putting concepts in a paper is hard, specially since different people
may interpret it in a different way.
Make clear about the meaning of the MEDIA_ENT_F_CONN_* entities
