Pull char/misc fixes from Greg KH:
"Here are some small char and misc driver fixes for 5.0-rc6.

Nothing huge here, some more binderfs fixups found as people use it,
and there is a "large" selftest added to validate the binderfs code,
which makes up the majority of this pull request.

There's also some small mei and mic fixes to resolve some reported
issues.

All of these have been in linux-next for over a week with no reported
issues"

things:

selftests: add binderfs selftests

This adds the promised selftest for binderfs. It will verify the following
things:
- binderfs mounting works
- binder device allocation works
- performing a binder ioctl() request through a binderfs device works
- binder device removal works
- binder-control removal fails
- binderfs unmounting works

The tests are performed both privileged and unprivileged. The latter
verifies that binderfs behaves correctly in user namespaces.
