Merge tag 'driver-core-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

2014-12-15T00:10:09+00:00

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"

gpio: rename gpio_lock_as_irq to gpiochip_lock_as_irq

2014-10-28T16:30:59+00:00

This function actually operates on a gpio_chip, so its prefix should
reflect that fact for consistency with other functions defined in
gpio/driver.h.

gpio: drop owner assignment from platform_drivers

2014-10-20T14:20:31+00:00

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

gpio: dwapb: fix pointer to integer cast

2014-09-24T11:30:24+00:00

The statements BUG_ON(ctx == 0) was implicitly casting a pointer
to an integer for comparison. Do this with a bool test instead
to get away from sparse warnings.

GPIO: gpio-dwapb: Enable platform driver binding to MFD driver

2014-09-23T15:51:37+00:00

The Synopsys DesignWare APB GPIO driver only supports open firmware devices.
But, like Intel Quark X1000 SOC, which has a single PCI function exporting
a GPIO and an I2C controller, it is a Multifunction device. This patch is
to enable the current Synopsys DesignWare APB GPIO driver to support the
Multifunction device which exports the designware GPIO controller.
