Subject: [PATCH v2 9/9] iio: adc: ad7173: Reduce device info struct size
Date: Tue, 14 May 2024 10:22:54 +0300 [thread overview]
Message-ID: <20240514-ad4111-v2-9-29be6a55efb5@analog.com> (raw)
In-Reply-To: <20240514-ad4111-v2-0-29be6a55efb5@analog.com>
From: Dumitru Ceclan <dumitru.ceclan@analog.com>
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.
