Subject: [PATCH v4 9/8] iio: adc: ad7124: Benefit of dev =
 indio_dev->dev.parent in ad7124_parse_channel_config()

Since commit a6eaf02b8274 ("iio: adc: ad7124: Switch from of specific to
fwnode based property handling") the function
ad7124_parse_channel_config() has a parameter `dev` that holds
the value `indio_dev->dev.parent`. Make use of that to shorten two code
lines.

Hello,

this is a patch opportunity I noticed while backporting my original
series to an older kernel to please my customer.
I chose to sneak it into the series in the hope to not offend maintainer
tools :-)

Best regards
Uwe
