Input: snvs_pwrkey - initialize necessary driver data before enabling IRQ
Anson Huang authored 
commit bf2a7ca3 upstream.

SNVS IRQ is requested before necessary driver data initialized,
if there is a pending IRQ during driver probe phase, kernel
NULL pointer panic will occur in IRQ handler. To avoid such
scenario, just initialize necessary driver data before enabling
IRQ. This patch is inspired by NXP's internal kernel tree.

Fixes: d3dc6e23

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.
