From 9be91db2efcf749eb159c674915d38e5ac14682a Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Thu, 8 Oct 2015 17:33:47 -0300 Subject: [media] demux.h: Convert MPEG-TS demux caps to an enum While we can't document #defines, documenting enums are well supported by kernel-doc. So, convert the bitmap defines into an enum.
