pronto: AU_LINUX_ANDROID_LNX.LA.3.5.1_RB1.04.04.02.048.042

* This is the closest caf tag to vs985's pronto driver. LG's
  source has all the comments stripped out, so shipping the caf
  branch is cleaner. We use the vs985 pronto firmware since
  d851, which this tree was originally created with, uses a
  broadcom chip.
