Mika Westerberg 72923e5488 Revert "pinctrl: intel: Do pin translation when lock IRQ" 
This reverts commit 55aedef50d.

Commit 55aedef50d ("pinctrl: intel: Do pin translation when lock IRQ")
added special translation from GPIO number to hardware pin number to
irq_reqres/relres hooks to avoid failure when IRQs are requested. The
actual failure happened inside gpiochip_lock_as_irq() because it calls
gpiod_get_direction() and pinctrl-intel.c::intel_gpio_get_direction()
implementation originally missed the translation so the two hooks made
it work by skipping the ->get_direction() call entirely (it overwrote
the default GPIOLIB provided functions).

The proper fix that adds translation to GPIO callbacks was merged with
commit 96147db1e1 ("pinctrl: intel: Do pin translation in other GPIO
operations as well"). This allows us to use the default GPIOLIB provided
functions again.

In addition as find out by Benjamin Tissoires the two functions
(intel_gpio_irq_reqres()/intel_gpio_irq_relres()) now cause problems of
their own because they operate on pin numbers and pass that pin number
to gpiochip_lock_as_irq() which actually expects a GPIO number.

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
