Merge git://git.kernel.org/pub/scm/linux/kernel/git/brodo/pcmcia-2.6
* git://git.kernel.org/pub/scm/linux/kernel/git/brodo/pcmcia-2.6: (50 commits) pcmcia: rework the irq_req_t typedef pcmcia: remove deprecated handle_to_dev() macro pcmcia: pcmcia_request_window() doesn't need a pointer to a pointer pcmcia: remove unused "window_t" typedef pcmcia: move some window-related code to pcmcia_ioctl.c pcmcia: Change window_handle_t logic to unsigned long pcmcia: Pass struct pcmcia_socket to pcmcia_get_mem_page() pcmcia: Pass struct pcmcia_device to pcmcia_map_mem_page() pcmcia: Pass struct pcmcia_device to pcmcia_release_window() drivers/pcmcia: remove unnecessary kzalloc pcmcia: correct handling for Zoomed Video registers in topic.h pcmcia: fix printk formats pcmcia: autoload module pcmcia pcmcia/staging: update comedi drivers PCMCIA: stop duplicating pci_irq in soc_pcmcia_socket PCMCIA: ss: allow PCI IRQs > 255 PCMCIA: soc_common: remove 'dev' member from soc_pcmcia_socket PCMCIA: soc_common: constify soc_pcmcia_socket ops member PCMCIA: sa1111: remove duplicated initializers PCMCIA: sa1111: wrap soc_pcmcia_socket to contain sa1111 specific data ...
