Claudiu Beznea 5d051cf94f mfd: atmel-flexcom: Use .resume_noirq 
Flexcom IP embeds 3 other IPs: usart, i2c, spi and selects the operation
mode (usart, i2c, spi) via mode register (FLEX_MR). On i2c bus there might
be connected critical devices (like PMIC) which on suspend/resume should
be suspended/resumed at the end/beginning. i2c uses
.suspend_noirq/.resume_noirq for this kind of purposes. Align flexcom
to use .resume_noirq as it should be resumed before the embedded IPs.
Otherwise the embedded devices might behave badly.

Fixes: 7fdec11015 ("atmel_flexcom: Support resuming after a chip reset")

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.
