[PATCH v3 6/6] iio: adc: ad7173: Reduce device info struct size

From: Dumitru Ceclan via B4 Relay
Date: Mon May 27 2024 - 13:04:27 EST


From: Dumitru Ceclan <dumitru.ceclan@xxxxxxxxxx>

Reduce the size used by the device info struct by packing the bool
fields within the same byte. This reduces the struct size from 52 bytes
to 44 bytes.
