Linus Walleij 17fdf318f5 ASoC: pcm6240: Drop bogus code handling IRQ as GPIO
The current code for the IRQ in pcm6240 makes no sense:
it looks up an IRQ with of_irq_get(), treat it as a GPIO
by issuing gpio_request(), gpio_direction_input()
and gpio_to_irq() on it.

This is just wrong, if the device tree assigns the IRQ
from a GPIO number this is just incorrect: it is clearly
stated that GPIO providers and IRQ providers are
orthogonal.

It is possible to look up an IRQ to a corresponding GPIO
line but this is taking an IRQ and pretending it's a
GPIO, which is just semantically wrong.

Drop the offending code and treat the IRQ that we get
from the device tree as any other IRQ, see for example
other codec drivers.

The DT bindings for this codec does not have any in-tree
DTS files, which may explain why things are weird.

As a bonus, this moves the driver away from the legacy
<linux/gpio.h> include.

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 reStructuredText markup notation.

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.
