Merge tag 'driver-core-4.1-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core fixes from Greg KH:
"Here are two fixes for the driver core that resolve some reported
issues.
One is a regression from 4.0, the other a fixes a reported oops that
has been there since 3.19.
Both have been in linux-next for a while with no problems"
* tag 'driver-core-4.1-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core:
drivers/base: cacheinfo: handle absence of caches
drivers: of/base: move of_init to driver_init
