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.

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.
