Merge tag 'driver-core-4.15-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core fixes from Greg KH:
"Here are two driver core fixes for 4.15-rc6, resolving some reported
issues.
The first is a cacheinfo fix for DT based systems to resolve a
reported issue that has been around for a while, and the other is to
resolve a regression in the kobject uevent code that showed up in
4.15-rc1.
Both have been in linux-next for a while with no reported issues"
* tag 'driver-core-4.15-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core:
kobject: fix suppressing modalias in uevents delivered over netlink
drivers: base: cacheinfo: fix cache type for non-architected system cache
