Combine the polarity_change flag, struct line eflags, and hte enable flag into a single flag variable. The combination of these flags describes the configuration state of the edge detector, so formalize and clarify that by combining them into a single variable, edflags, in struct line. The edflags is a subset of the GPIO_V2_LINE_FLAGsb relevant to the edge detector, and is also a superset of the eflags it replaces. The eflags name is still used to describe the subset of edflags corresponding to the rising/falling edge flags where edflags is masked down to that subset. This consolidation reduces the number of variables being passed, simplifies state comparisons, and provides a more extensible foundation should additional edge sources be integrated in the future.

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.
