Hi,

This series fixes two issues in the FP9931/JD9930 regulator driver.

Patch 1 fixes an off-by-one error in the VPOS/VNEG voltage selector
table and aligns it with the datasheet-defined voltage mapping [1].

Patch 2 fixes a Runtime PM reference counting bug in the V3P3 regulator
callbacks that can lead to "Runtime PM usage count underflow!" warnings.

Thanks,
Robby
