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
