Pull driver core update from Greg KH:
"Here's the set of driver core patches for 3.19-rc1.
They are dominated by the removal of the .owner field in platform
drivers. They touch a lot of files, but they are "simple" changes,
just removing a line in a structure.
Other than that, a few minor driver core and debugfs changes. There
are some ath9k patches coming in through this tree that have been
acked by the wireless maintainers as they relied on the debugfs
changes.
Everything has been in linux-next for a while"

The only place where the time is invalid is when the ACPI_CSTATE_FFH entry
method is not set. Otherwise for all the drivers, the time can be correctly
measured.
Instead of duplicating the CPUIDLE_FLAG_TIME_VALID flag in all the drivers
for all the states, just invert the logic by replacing it by the flag
CPUIDLE_FLAG_TIME_INVALID, hence we can set this flag only for the acpi idle
driver, remove the former flag from all the drivers and invert the logic with
this flag in the different governor.

A platform_driver does not need to set an owner, it will be populated by the
driver core.

This commit adds the list of cpuidle states supported by the Armada
38x SoC in the cpuidle-mvebu-v7 driver, as well as the necessary logic
around it to support this SoC.

This driver will be able to manage the cpuidle for more SoCs than just
Armada 370 and XP. It will also support Armada 38x and potentially
other SoC of the Marvell Armada EBU family. To take this into account,
this patch renames the driver and its symbols.
It also changes the driver name from cpuidle-armada-370-xp to
cpuidle-armada-xp, because separate platform drivers will be
registered for the other SoC types. This change must be done
simultaneously in the cpuidle driver and in the PMSU code in order to
remain bisectable.
