commit 8a092e682f20f193f2070dba2ea1904e95814126 upstream.
Bypass support was added in commit d38018f2019c ("regulator: anatop: Add bypass support to digital LDOs"). A check for valid voltage selectors was added in commit da0607c8df5c ("regulator: anatop: Fail on invalid voltage selector") but it also discards all regulators that are in bypass mode. Add check for the bypass setting. Errors below were seen on a Variscite mx6 board.
