Subject: [PATCH v3 0/6] gpio / ACPI: convert users to gpiod_* and drop acpi_gpio.h

Hi all,

Now that the mainline kernel has full ACPI support for the GPIO descriptor
interface we can get rid of ACPI specific GPIO functions in favor of GPIO
descriptor (gpiod_*) interfaces.

This series first converts the existing two users to this interface and
then modifies gpiolib and gpiolib-acpi so that the ACPI functions are only
called internally in drivers/gpio. We then remove the acpi_gpio.h and
require all users to use gpiod_* interfaces.

This is third version of the series. Changes to the previous version [1]:

 * Instead of adding temporary conversion from GPIO descriptors to numbers
   in rfkill-gpio.c we now first introduce a lookup table for paz00 and
   in the next patch convert the driver to use only GPIO descriptors.

 * Corrected a typo in subject of patch [3/6] "covert" -> "convert".

 * Corrected a typo in changelog of patch [5/6] "user" -> "use".

 * Dropped EXPORT_SYMBOL_GPL(acpi_get_gpiod_by_index) from patch [5/6] that
   was left there accidentally.

Since the patches in the series depend on each other I would propose this
to be merged via GPIO tree.
