[FFmpeg-devel] [PATCH 06/13] arm: vp9itxfm: Rename a macro parameter to fit better

[Martin Storsjö]

Since the same parameter is used for both input and output,
the name inout is more fitting.

This matches the naming used below in the dmbutterfly macro.

This is cherrypicked from libav commit
79566ec8c77969d5f9be533de04b1349834cca62.
