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

Pull pcmcia updates from Dominik Brodowski:
 "Besides a few PCMCIA odd fixes, the NEC VRC4173 CARDU driver is
  removed, as it has not compiled in ages"

* 'pcmcia-next' of git://git.kernel.org/pub/scm/linux/kernel/git/brodo/linux:
  pcmcia: omap: Fix error return code in omap_cf_probe()
  pcmcia: Remove NEC VRC4173 CARDU
  pcmcia: db1xxx_ss: remove unneeded semicolon
  pcmcia/electra_cf: Fix some return values in 'electra_cf_probe()' in case of error
