Subject: [PATCH v2 09/10] iio: adc: ad7606: fix standby gpio state to match
the documentation
The binding's documentation specifies that "As the line is active low, it
should be marked GPIO_ACTIVE_LOW". However, in the driver, it was handled
the opposite way. This commit sets the driver's behaviour in sync with the
documentation
Fixes: 722407a4e8c0 ("staging:iio:ad7606: Use GPIO descriptor API")
