Merge tag 'char-misc-5.2-rc1-part1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char/misc update part 1 from Greg KH:
"This contains only a small number of bugfixes that would have gone to
you for 5.1-rc8 if that had happened, but instead I let them sit in
linux-next for an extra week just "to be sure".
The "big" patch here is for hyper-v, fixing a bug in their sysfs files
that could cause big problems. The others are all small fixes,
resolving reported issues that showed up in 5.1-rcs, plus some odd
'static' cleanups for the phy drivers that really should have waited
for -rc1. Most of these are tagged for the stable trees, so 5.1 will
pick them up.
All of these have been in linux-next for a while, with no reported
issues"
