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.

This patch adds the support for S2MPS13 PMIC clock which is same with existing
S2MPS14 RTC IP. But, S2MPS13 uses all of clocks (32khz_{ap|bt|cp}).

s2mps11 clocks had registered callbacks for prepare ,unprepare and is_enabled.
During disabling unused clocks the lack of is_prepared caused that unused
s2mps11 clocks were not unprepared and stayed active.
Regmap_read is cached so it can be called in is_prepare callback
to achieve this information. Enabled field was removed from struct s2mps11_clk.

There is no need for checking if 'clk_table' is not NULL twice (first
after allocation and second at the end of probe()). Also move allocation
of this 'clk_table' to probe from s2mps11_clk_parse_dt as this is
logical place for it.

If parent device does not have of_node set the s2mps11_clk_parse_dt()
returned NULL. This NULL was later passed to of_clk_add_provider() which
dereferenced it in pr_debug() call.

Since clock operation within S2MPS11 and S5M8767 are similar, we can
support both the devices within a single driver.

The clocks in S2MPS11 and S5M8767 are managed in the same way, baring
a difference in the register offset. It would be better to update
existing S2MPS11 driver to support the clocks in S5M8767, rather than
creating an almost duplicate driver altogether.
