Subject: [PATCH v3 6/6] iio: adc: ad7173: Reduce device info struct size
Date: Mon, 27 May 2024 20:02:39 +0300 [thread overview]
Message-ID: <20240527-ad4111-v3-6-7e9eddbbd3eb@analog.com> (raw)
In-Reply-To: <20240527-ad4111-v3-0-7e9eddbbd3eb@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.
Signed-off-by: Dumitru Ceclan <dumitru.ceclan@analog.com>
