[PATCH AUTOSEL 4.14 48/56] iio: adc: ad799x: fix probe error handling

[Sasha Levin <sashal@kernel.org>]

From: Marco Felsch <m.felsch@pengutronix.de>

[ 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.

Fixes: 0f7ddcc1bff1 ("iio:adc:ad799x: Write default config on probe and reset alert status on probe")
