Fabian Vogt dfed481e62 Input: nspire-keypad - enable interrupts only when opened 
[ Upstream commit 69d5ff3e9e51e23d5d81bf48480aa5671be67a71 ]

The driver registers an interrupt handler in _probe, but didn't configure
them until later when the _open function is called. In between, the keypad
can fire an IRQ due to touchpad activity, which the handler ignores. This
causes the kernel to disable the interrupt, blocking the keypad from
working.

Fix this by disabling interrupts before registering the handler.
Additionally, disable them in _close, so that they're only enabled while
open.

Fixes: fc4f314618 ("Input: add TI-Nspire keypad support")

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.

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.
