Merge tag 'spi-v3.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi

Pull spi fixes from Mark Brown:
 "A couple of things missed during the v3.11 work here:

   - The spi-bitbang core requires a setup() function even if it does
     nothing which caused breakage when some empty setup functions were
     removed after their contents were factored out into the core.

     While this is clearly silly and will be fixed for v3.12 for now we
     just restore the functions.

   - A missing case handled in the s3c64xx driver"
