   4 Subject: [PATCH] staging: bcm2835-audio: don't initialize memory twice
   5
   6 commit 2e5f59fb77397cab3bc3d156e8be4164a67d32ef upstream.
   7
   8 The memory is being allocated with devres_alloc(), wich ultimately uses
   9 __GFP_ZERO to call kmalloc. We don't need to zero the memory area again
  10 in bcm2835-audio.
