Merge tag 'fsi-updates-2018-07-27' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/linux-fsi into char-misc-next
Ben writes:
Last round of FSI updates for 4.19
This adds a few fixes for things reported since the last merge,
and the latch batch of changes pending for FSI for 4.19.
That batch is a rather mechanical conversion of the misc devices
into proper char devices.
The misc devices were ill suited, the minor space for them is
limited and we can have a lot of chips in a system creating FSI
devices.
This also allows us to better control (and fix) object lifetime
getting rid of the bad devm_kzalloc() of the structures containing
the devices etc...
Finally, we add a chardev to the core FSI that provides raw CFAM
access to FSI slaves as a replacement for the current "raw" binary
sysfs file which will be ultimately deprecated and removed.
