Roger's promised to test it once suspend regression will be fixed
for dra7-evm, probably next rc.

This issue is here since 2012, so I think it's not very critical -
It seems bits combination which causing the issue is rare.

Regarding stable:
4.4 - good to have, simple merge conflict
4.1 - some merge resolution is required
older kernel - it will be hard to backport it due to significant
changes in omap gpio driver

Santosh, Tony, do you want me to perform any additional actions regarding this patch?
