   ipmi: Properly release srcu locks on error conditions (2018-05-24 
15:08:30 -0500)

----------------------------------------------------------------
It's been a busy release for the IPMI driver.  Some notable changes:

A user was running into timeout issues doing maintenance commands over
the IPMB network behind an IPMI controller.  Extend the maintenance
mode concept to messages over IPMB and allow the timeouts to be tuned.

Lots of cleanup, style fixing, some bugfixes, and such.

At least one user was having trouble with the way the IPMI driver would
lock the i2c driver module it used.  The IPMI driver was not designed
for hotplug.  However, hotplug is a reality now, so the IPMI driver
was modified to support hotplug.

The proc interface code is now completely removed.  Long live sysfs!
