From: Emil Velikov <emil.velikov@xxxxxxxxxxxxx>
The file has been used for about 8 years now - see commit fb55b7a6a
("profiles/hog: Use no suspend support instead of the dummy FIFO").
Inspired by a Debian patch by Nobuhiro Iwamatsu, which was changing the
/tmp/hogsuspend socket patch to /run. Looking through the codebase we
have a few more sockets that could use a to /run fix, but that will
follow-up at another day.
