Damien Riegel 8f75bc3377 Input: tca8418 - enable interrupt after it has been requested
Currently, enabling keypad interrupts is one of the first operations
done on the keypad, even before the interrupt is requested, so there is
a small time window where the keypad can fire interrupts but the driver
is not yet ready to handle them. It's fine for level interrupts because
they will be handled anyway, but not so much for edge ones.

This commit modifies and moves the function in charge of configuring the
keypad. Enabling interrupts is now the last thing done on the keypad,
and after the interrupt has been requested by the driver.

Writing to the config register was also used to determine if the device
was indeed present on the bus or not, this has been replaced by reading
the lock/event count register to keep the same functionality.

README

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

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

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.
