Merge branch 'urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/brodo/pcmcia-2.6 

* 'urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/brodo/pcmcia-2.6:
  pcmcia: fix error handling in cm4000_cs.c
  drivers/pcmcia: Add missing local_irq_restore
  serial_cs: MD55x support (PCMCIA GPRS/EDGE modem) (kernel 2.6.33)
  pcmcia: avoid late calls to pccard_validate_cis
  pcmcia: fix ioport size calculation in rsrc_nonstatic
  pcmcia: re-start on MFC override
  pcmcia: fix io_probe due to parent (PCI) resources
  pcmcia: use previously assigned IRQ for all card functions
parents ac8bf564 07a71415
