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"

When usb is connected and enumerated in device mode or when
usb is disconnected, call usb_phy_set_event() from phy drivers
to handle per-PHY event.

This patch prepares the introduction of the generic PHY support in the
USB OTG common functions. The USB PHY member of the OTG structure is
renamed to 'usb_phy' and modifications are done in all drivers accessing
it. Renaming this pointer will allow to keep the compatibility for USB
PHY drivers.

Before using the PHY framework instead of the USB PHY one, we need to
move the OTG state into another place, since it won't be available when
USB PHY isn't used. This patch moves the OTG state into the OTG
structure, and makes all the needed modifications in the drivers
using the OTG state.

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

Using kfree to free data allocated with devm_kzalloc causes double frees.
The Coccinelle semantic patch that fixes this problem is as follows:
// <smpl>
@@
expression x;
@@
x = devm_kzalloc(...)
...
?-kfree(x);
// </smpl>

The various devm_ functions allocate memory that is released when a
driver detaches. This patch uses devm_kzalloc, devm_request_irq,
devm_gpio_request, devm_regulator_get etc. for data that is
allocated in the probe function of a platform device and is only
freed in the remove function. The corresponding free functions are
removed and the labels are done away with.

We need to initialize the notifer before use it.
So lets initialize it when add a new phy device to
reduce the code redundancy.

Move probe out of __init section and don't use platform_driver_probe
which cannot be used with deferred probing.
Since commit e9354576 ("gpiolib: Defer failed gpio requests by default")
and 04bf3011 ("regulator: Support driver probe deferral") this driver
might return -EPROBE_DEFER if a gpio_request or regulator_get fails.

Upon initialisation (driver probe) a NULL pointer exception
is triggered. This is due to lack of initialisation of
device field in phy structure, which is used by phy
framework in usb_get_phy().
Fix it by initialising the device field.

Due to recent changes to regulator API, all
users which don't check regulator_{en,dis}able()'s
return value will generate compile warnings.
Add such checks to gpio-vbus.

this will make sure that we have sensible names
for all phy drivers. Current situation was already
quite bad with too generic names being used.
