commit1a5287a3dbupstream. During noirq suspend/resume phase, GPIO irq could arrive and its registers like IMR will be changed by irq handle process, to make the GPIO registers exactly when it is powered ON after resume, move the GPIO noirq suspend/resume callback to syscore suspend/resume phase, local irq is disabled at this phase so GPIO registers are atomic.

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.
