* git://git.kernel.org/pub/scm/linux/kernel/git/brodo/pcmcia-2.6: pcmcia: avoid buffer overflow in pcmcia_setup_isa_irq pcmcia: do not request windows if you don't need to pcmcia: insert PCMCIA device resources into resource tree pcmcia: export resource information to sysfs pcmcia: use struct resource for PCMCIA devices, part 2 pcmcia: remove memreq_t pcmcia: move local definitions out of include/pcmcia/cs.h pcmcia: do not use io_req_t when calling pcmcia_request_io() pcmcia: do not use io_req_t after call to pcmcia_request_io() pcmcia: use struct resource for PCMCIA devices pcmcia: clean up cs.h pcmcia: use pcmica_{read,write}_config_byte pcmcia: remove cs_types.h pcmcia: remove unused flag, simplify headers pcmcia: remove obsolete CS_EVENT_ definitions pcmcia: split up central event handler pcmcia: simplify event callback pcmcia: remove obsolete ioctl Conflicts in: - drivers/staging/comedi/drivers/* - drivers/staging/wlags49_h2/wl_cs.c due to dev_info_t and whitespace changes
