Marc Zyngier 32280649f0 mfd: Don't use irq_create_mapping() to resolve a mapping
[ Upstream commit 9ff80e2de36d0554e3a6da18a171719fe8663c17 ]

Although irq_create_mapping() is able to deal with duplicate
mappings, it really isn't supposed to be a substitute for
irq_find_mapping(), and can result in allocations that take place
in atomic context if the mapping didn't exist.

Fix the handful of MFD drivers that use irq_create_mapping() in
interrupt context by using irq_find_mapping() instead.

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.
