Alistair Popple	ad1ed2a9dd	ipmi/powernv: Fix minor locking bug ... If ipmi_powernv_recv(...) is called without a current message it prints a warning and returns. However it fails to release the message lock causing the system to dead lock during any subsequent IPMI operations. This error path should never normally be taken unless there are bugs elsewhere in the system.

Jeremy Kerr	6a11e5c67a	drivers/char/ipmi: Add powernv IPMI driver ... This change adds an initial IPMI driver for powerpc OPAL firmware. The interface is exposed entirely through firmware: we have two functions to send and receive IPMI messages, and an interrupt notification from the firmware to signify that a message is available.
