Merge tag 'driver-core-3.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core patches from Greg KH:
"Really tiny set of patches for this kernel. Nothing major, all
described in the shortlog and have been in linux-next for a while"
* tag 'driver-core-3.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core:
sysfs: fix warning when creating a sysfs group without attributes
firmware_loader: handle timeout via wait_for_completion_interruptible_timeout()
firmware_loader: abort request if wait_for_completion is interrupted
firmware: Correct function name in comment
device: Change dev_<level> logging functions to return void
device: Fix dev_dbg_once macro
