From: Jon Hunter <[email protected]> When checking the bypass state for a regulator, we check to see if any bits in the bypass mask are set. For most cases this is fine because there is typically only a single bit used to determine if the regulator is in bypass. However, for some regulators, such as LDO6 on AS3722, the bypass state is indicated by a value rather than a single bit.
Therefore, when checking the bypass state, check that the bypass field matches the ON value.
