Pull IPMI fixes from Corey Minyard:
 "Lots of minor IPMI fixes, especially ones that have have come up since
  the SSIF driver has been in the main kernel for a while"

* tag 'for-linus-4.1-1' of git://git.code.sf.net/p/openipmi/linux-ipmi:
  ipmi: Fix multi-part message handling
  ipmi: Add alert handling to SSIF
  ipmi: Fix a problem that messages are not issued in run_to_completion mode
  ipmi: Report an error if ACPI _IFT doesn't exist
  ipmi: Remove unused including <linux/version.h>
  ipmi: Don't report err in the SI driver for SSIF devices
  ipmi: Remove incorrect use of seq_has_overflowed
  ipmi:ssif: Ignore spaces when comparing I2C adapter names
  ipmi_ssif: Fix the logic on user-supplied addresses
