Subject[PATCH 0/2] regulator: vctrl: Avoid lockdep warning in enable/disable ops
Date
Hi,

Here are a couple fixes for vctrl-regulator. This driver is only used
RK3399-based Chromebooks.

Patch one fixes a misuse of the regulator API, which was found while
tracing the code to fix the lockdep warning.

Patch two fixes a lockdep warning and actual (not easy to reproduce)
deadlock.

Please have a look. The are no dependencies between the two patches.


Additionally, I believe it would make sense to implement the voltage
stepping feature for all regulators in the core. Then we could move
away from vctrl-regulator. Right now it is only done for coupled
regulators.


Regards
ChenYu
