Merge tag 'char-misc-3.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull char/misc updates from Greg KH:
 "Here's the big char/misc driver tree merge for 3.11-rc1

  A variety of different driver patches here.  All of these have been in
  linux-next for a while, and the networking patches were acked-by David
  Miller, as it made sense for those patches to come through this tree"

* tag 'char-misc-3.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (102 commits)
  Revert "char: misc: assign file->private_data in all cases"
  drivers: uio_pdrv_genirq: Use of_match_ptr() macro
  mei: check whether hw start has succeeded
  mei: check if the hardware reset succeeded
  mei: mei_cl_connect: don't multiply the timeout twice
  mei: do not override a client writing state when buffering
  mei: move mei_cl_irq_write_complete to client.c
  UIO: Fix concurrency issue
  drivers: uio_dmem_genirq: Use of_match_ptr() macro
  char: misc: assign file->private_data in all cases
  drivers: hv: allocate synic structures before hv_synic_init()
  drivers: hv: check interrupt mask before read_index
  vme: vme_tsi148.c: fix error return code in tsi148_probe()
  FMC: fix error handling in probe() function
  fmc: avoid readl/writel namespace conflict
  FMC: NULL dereference on allocation failure
  UIO: fix uio_pdrv_genirq with device tree but no interrupt
  UIO: allow binding uio_pdrv_genirq.c to devices using command line option
  FMC: add a char-device mezzanine driver
  FMC: add a driver to write mezzanine EEPROM
