Driver Probe Deferral Mechanism

Original patch posted at:
http://comments.gmane.org/gmane.linux.kernel/1194346

Enhancements done to above patch:
 - checkpatch warning fixes
 - added Kconfig symbol CONFIG_PROBE_DEFER
 - replacing normal workqueue with singlethread_workqueue
 - handling -EPROBE_DEFER error

Apart from that, OMAP HSMMC and GPIO drivers are adopted to use
deferral probe mechanism and successfully tested on omap3 beagle
board.

Applies cleanly on top of v3.1-rc8

G, Manjunath Kondaiah (3):
  drivercore: add new error value for deferred probe
  gpiolib: handle deferral probe error
  omap: hsmmc: use platform_driver_register

Grant Likely (1):
  drivercore: Add driver probe deferral mechanism

Mark Brown (1):
  regulator: Support driver probe deferral
