   4 Subject: [PATCH 465/806] staging: bcm2835-audio: reorder variable declarations
   5  & remove trivial comments
   6
   7 commit d048385a070552ae819f99f05bd03ec41072783d upstream.
   8
   9 When it comes to declaring variables it's preferred, when possible, to
  10 use an inverted tree organization scheme.
  11
  12 Also, removes some comments that were useless.
