Pull pcmcia updates from Dominik Brodowski:
 "A number of odd cleanups and fixes, including one for a small race in
  the handling of the pccardd kernel thread"

* 'pcmcia-next' of git://git.kernel.org/pub/scm/linux/kernel/git/brodo/linux:
  pcmcia: fix setting of kthread task states
  MAINTAINERS: update PCMCIA tree
  pcmcia: use sysfs_emit{,_at} for sysfs output
  pcmcia: make pcmcia_release_io() void, as no-one is interested in return value
  pcmcia: rsrc_nonstatic: Fix a NULL pointer dereference in nonstatic_find_mem_region()
  pcmcia: rsrc_nonstatic: Fix a NULL pointer dereference in __nonstatic_find_io_region()
  pcmcia: comment out unused exca_readw() function
  pcmcia: Make use of the helper macro SET_NOIRQ_SYSTEM_SLEEP_PM_OPS()
  pcmcia: clean up dead drivers for CompuLab CM-X255/CM-X270 boards
