Merge ipmi fixes from Corey Minyard: "Just some collected fixes for 3.14. Nothing huge" * emailed patches from Corey Minyard <minyard@acm.org>: ipmi: Cleanup error return ipmi: fix timeout calculation when bmc is disconnected ipmi: use USEC_PER_SEC instead of 1000000 for more meaningful ipmi: remove deprecated IRQF_DISABLED
