Aneesh Kumar K.V 7844663a31 powerpc/eeh: Don't release eeh_mutex in eeh_phb_pe_get 
Acked-by: Gavin Shan <shangw@linux.vnet.ibm.com>

=====================================
[ BUG: bad unlock balance detected! ]
3.6.0-rc5-00338-gcaa1d63-dirty #6 Not tainted
-------------------------------------
swapper/0/1 is trying to release lock (eeh_mutex) at:
[<c000000000058218>] .eeh_add_to_parent_pe+0x318/0x410
but there are no more locks to release!

other info that might help us debug this:
no locks held by swapper/0/1.

stack backtrace:
