The lan743x_ptp_io_event_cap_en() function checks that the given request
sets only one of PTP_RISING_EDGE or PTP_FALLING_EDGE, but not both.
However, this driver does not check whether other flags (such as
PTP_EXT_OFF) are set, nor whether any future unrecognized flags are set.
Fix this by adding the appropriate check to the lan743x_ptp_io_extts()
function.

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 reStructuredText 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.
