The status of the keys connected to the KPDPWR_N and RESIN_N pins is identified by reading corresponding bits in the interrupt real time status register. If the status has changed by the time that the interrupt is handled then a press event will be missed. Maintain a last known status variable to find unbalanced release events and simulate press events for each accordingly.

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.
