The rtc-max77686 device shares the main interrupt line with parent MFD device (max77686 driver). During the system suspend, the parent MFD device disables this IRQ to prevent an early event happening before resuming I2C bus controller. The same should be done by rtc-max77686 driver because otherwise the interrupt handler max77686_rtc_alarm_irq() will be called before its resume function (max77686_rtc_resume()). Such issue is not fatal but disabling shared IRQ by all users ensures correct behavior.

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.
