Subject: media: vicodec: fix g_selection: either handle crop or compose
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=fb56f4be05adb64674a8a4ec230090960a61732e;p=android-x86%2Fkernel.git

media: vicodec: fix g_selection: either handle crop or compose

The logic of g_selection was wrong: encoders support crop,
decoders support compose, but the code allowed both.
