Subject: [PATCH] staging: bcm2835-audio: Remove redundant function
calls
commit 124950ebe9fa8547c59e8d4acc8d6c59e6278ed6 upstream.
bcm2835_audio_setup(), bcm2835_audio_flush_buffers() and
bcm2835_audio_flush_playback_buffers() functions do implement
nothing.
Also, bcm2835_audio_set_ctls() is already called inside
bcm2835_audio_set_params(), so the later call is superfluous.
This patch removes these superfluous implementations.
