Himangi Saraogi 9f7b23ce88 usb: phy: phy-gpio-vbus-usb: use devm_ functions
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.

Neil Zhang 31e322272d usb: phy: initialize the notifier when add a new phy
We need to initialize the notifer before use it.

So lets initialize it when add a new phy device to
reduce the code redundancy.

Johan Hovold eaaa775b5f usb: phy: gpio-vbus: fix deferred probe from __init
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.

Jingoo Han 19f9e188de usb: phy: use dev_get_platdata()
Use the wrapper function for retrieving the platform data instead of
accessing dev->platform_data directly.

Robert Jarzmik 1abd8b3172 usb: phy: Fix NULL pointer exception during usb_get_phy
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.

Commit 0998d06310 (device-core: Ensure drvdata = NULL when no
driver is bound) removes the need to set driver data field to
NULL.

Felipe Balbi e8d891fb7b usb: phy: gpio-vbus: don't ignore regulator APIs return value
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.

Felipe Balbi 94ae98433a usb: phy: rename all phy drivers to phy-$name-usb.c
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.
