   4 Subject: [PATCH] staging: bcm2835-audio: Drop unnecessary pcm indirect
   5  setup
   6
   7 commit 7318ec896f4856fae2bb013858e422fa078201e1 upstream.
   8
   9 The hw_queue_size of PCM indirect helper doesn't need to be set up if
  10 you use the whole given buffer size.  Drop the useless
  11 initialization, which just confuses readers.
