This patch series introduces support for voltage supply, I2C and cathode
regulators. This fixes an issue where if a regulator is shared between
the proximity sensor and some other device, and the other device is
powered off, the proximity sensor would be powered off as well.

One of the commits includes a Reported-by: tag without a Closes: tag -
the report was done outside of LKML.
