This removes the no longer required setting of the module owner
for the plaform structure,powernv_ipmi_driver to THIS_MODULE as
the driver core for ipmi drivers will directly find and
set the module owner for this driver.

ipmi/powernv: Fix potential invalid pointer dereference2015-09-03T20:01:55ZNeelesh Guptaneelegup@linux.vnet.ibm.com2015-07-16T11:16:54Zurn:sha1:cca85f19c260df495a487495479c67803b25fa8a
If the OPAL call to receive the ipmi message fails, then we free up the
smi message and return. But, the driver still holds the reference to
old smi message in the 'cur_msg' which can potentially be accessed later
and freed again leading to kernel oops. To fix it up,
The kernel driver should reset the 'cur_msg' and send reply to the user
in addition to freeing the message.

ipmi/powernv: Fix minor locking bug2015-04-11T01:51:42ZAlistair Popplealistair@popple.id.au2015-04-10T07:32:20Zurn:sha1:ad1ed2a9dd4c435d6a3ce470211db9a8d107c3e0
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.

drivers/char/ipmi: Add powernv IPMI driver2014-12-11T21:04:12ZJeremy Kerrjk@ozlabs.org2014-11-12T07:41:05Zurn:sha1:6a11e5c67a397e9a64cfde6961c83a7a64d7980c
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.
