  serial: msm_serial_hs: Add MSM high speed UART driver
  tty_audit: fix tty_audit_add_data live lock on audit disabled
  tty: move cd1865.h to drivers/staging/tty/
  Staging: tty: fix build with epca.c driver
  pcmcia: synclink_cs: fix prototype for mgslpc_ioctl()
  Staging: generic_serial: fix double locking bug
  nozomi: don't use flush_scheduled_work()
  tty/serial: Relax the device_type restriction from of_serial
  MAINTAINERS: Update HVC file patterns
  tty: phase out of ioctl file pointer for tty3270 as well
  tty: forgot to remove ipwireless from drivers/char/pcmcia/Makefile
  pch_uart: Fix DMA channel miss-setting issue.
  pch_uart: fix exclusive access issue
  pch_uart: fix auto flow control miss-setting issue
  pch_uart: fix uart clock setting issue
  pch_uart : Use dev_xxx not pr_xxx
  ...

Fix up trivial conflicts in drivers/misc/pch_phub.c (same patch applied
twice, then changes to the same area in one branch)
