Commit 314489bd authored by Linus Torvalds's avatar Linus Torvalds

Merge tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull "ARM: SoC fixes: from Olof Johansson:
 "A bunch of fixes for regressions (and a few other problems) in
  3.4-rc1:

 - Fix for regression of mach/io.h cleanup on platforms with PCI or
   PCMCIA (adding back the include file on those for now)
 - AT91 fixes for usb and spi
 - smsc911x ethernet fixes for i.MX
 - smsc911x fixes for OMAP
 - gpio fixes for Tegra
 - A handful of build error and warning fixes for various platforms
 - cpufreq kconfig dependencies, build and lowlevel debug fixes for
   Samsung platforms

  In other words, more or less the regular collection of -rc1/2 type
  material.  A few of them, in particular the smsc911x for OMAP series,
  aren't technically regressions for 3.4, but they're valid fixes and
  we're still relatively early in the rc cycle so it seems appropriate
  to include them."
