Merge git://git.kernel.org/pub/scm/linux/kernel/git/brodo/pcmcia 

Pull PCMCIA update from Dominik Brodowski:
 "A few PCMCIA fixes and cleanups are available in the PCMCIA tree.

  Most of them are trivial and self-explanatory.  Of particular note are
  the last three patches which add an important hardware quirk for
  Toshiba ToPIC95 sockets (or BIOS breakage on systems with these
  sockets), fix resource leaks in yenta_socket enable/disable call
  paths, and fix a regression caused by patch 1c6c9b1d since v4.0.

  Alan stated he is OK with me pushing this patch upstream.  Once it
  works out well in your tree, I will push it to stable for 4.0/4.1 as
  well"

* git://git.kernel.org/pub/scm/linux/kernel/git/brodo/pcmcia:
  pcmcia: do not break rsrc_nonstatic when handling anonymous cards
  pcmcia: Fix resource leaks in yenta_probe() and _close()
