From ee492cfcb17631e4345fa97f205ca9617fffaebc Mon Sep 17 00:00:00 2001 From: Marek Belisko Date: Thu, 25 Apr 2013 15:13:12 +0200 Subject: ASoC: spdif_transceiver: Change driver filename to spdif_transmitter.c. Transceiver usually means receiver + transmitter. This codec can do only transmit. Update driver accordingly.
