Subject: [media] demux.h: Convert MPEG-TS demux caps to an enum
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9be91db2efcf749eb159c674915d38e5ac14682a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[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.
