   4 Subject: [PATCH] staging: mt7621-pci: don't return if get gpio fails
   5
   6 In some platforms gpio's are not used for reset but
   7 for other purposes. Because of that when we try to
   8 get them are valid gpio's but are already assigned
   9 to do other function. To avoid those kind of problems
  10 in those platforms just notice the fail in the kernel
  11 but continue doing normal boot.
