Merge tag 'for-linus-5.1-2' of git://github.com/cminyard/linux-ipmi 

Pull IPMI fixes from Corey Minyard:
 "Fixes for some bugs cause by recent changes. One crash if you feed bad
  data to the module parameters, one BUG that sometimes occurs when a
  user closes the connection, and one bug that cause the driver to not
  work if the configuration information only comes in from SMBIOS"

* tag 'for-linus-5.1-2' of git://github.com/cminyard/linux-ipmi:
  ipmi: fix sleep-in-atomic in free_user at cleanup SRCU user->release_barrier
  ipmi: ipmi_si_hardcode.c: init si_type array to fix a crash
  ipmi: Fix failure on SMBIOS specified devices
