Subject: [PATCH v3 07/10] iio: accel: mma8452: use local struct device
Date: Tue,  5 May 2026 23:16:37 +0530	[thread overview]
Message-ID: <20260505174640.3998281-8-sanjayembedded@gmail.com> (raw)
In-Reply-To: <20260505174640.3998281-1-sanjayembedded@gmail.com>

From: Sanjay Chitroda <sanjayembeddedse@gmail.com>

Introduce a local struct device pointer derived from &client->dev.
This avoids repeated &client->dev usage and improves readability.
