From: Marco Felsch <m.felsch@xxxxxxxxxxxxxx> [ Upstream commit c62dd44901cfff12acc5792bf3d2dec20bcaf392 ] Since commit 0f7ddcc1bff1 ("iio:adc:ad799x: Write default config on probe and reset alert status on probe") the error path is wrong since it leaves the vref regulator on. Fix this by disabling both regulators.
