   4 Subject: [PATCH] phy: phy-brcm-usb: Constify static structs
   5
   6 A number of structs were not modified and can therefore be made const
   7 to allow the compiler to put them in read-only memory.
   8
   9 In order to do so, update a few functions that don't modify there input
  10 to take pointers to const.
