Hi Greg ! 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. Thanks ! Ben.
