Subject[RFC PATCH] [media] rc: filter out not allowed protocols when decoding
Date
From: "Du, Changbin" <changbin.du@gmail.com>

Each rc-raw device has a property "allowed_protos" stored in structure
ir_raw_event_ctrl. But it didn't work because all decoders would be
called when decoding. This path makes only allowed protocol decoders
been invoked.
