This patch does NOT apply to the 3.12 stable tree. If you still want
it applied, please provide a backport.
===============
commit 086abb58590a4df73e8a6ed71fd418826937cd46 upstream.
In of_init_opp_table function, if a failure to add an OPP is
detected, the count of OPPs, yet to be added is not updated.
Fix this by decrementing this count on failure as well.
