James, i have just checked - the old patch (v3) applies cleanly onto latest master branch.

Well, back in the year 2019 i've created a bug in RedHat bugzilla
https://bugzilla.redhat.com/show_bug.cgi?id=1724077
(the bug is private, this is default for Redhat bugs)

In this bug Sagar Biradar (with the email @microchip.com) suggested me to rework the patch - i've done 
that and sent the v3.

And nothing happened after that, but in a ~year (2020-06-19) the bug was closed with the resolution 
NOTABUG and a comment that S6 users will find the patch useful.

i suppose S6 is so old that RedHat just does not have customers using it and Microchip company itself 
is also not that interested in handling so old hardware issues.

Sorry, i was unable to get a final ack from Microchip,
i've written direct emails to the addresses which is found in the internet, tried to connect via 
linkedin, no luck.
