Subject[PATCH 0/2] regulator: Fix regulator_enable deadlock and add uA_load propagation
DateMon, 28 Mar 2011 08:34:40 -0700
Because the uA_load propagation change takes out a lock on a regulator and
then the regulators that it supplies, it will cause deadlock with the current
regulator_enable implementation. regulator_disable can also deadlock with
regulator_enable, but it requires two threads and precise timing to observe.
Therefore, regulator_enable must be fixed before current propagation can be
used.

David Collins (2):
regulator: Remove possible deadlock from regulator_enable
regulator: Propagate uA_load requirements up supply chain
