Merge branch 'pcmcia-next' of git://git.kernel.org/pub/scm/linux/kernel/git/brodo/linux
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
