[PATCH v4 24/36] iio: pressure: hid-sensor-press: use local struct device
From: Sanjay Chitroda <hidden>
Date: 2026-05-24 19:28:36
Also in:
linux-iio, lkml
Subsystem:
hid sensor hub drivers, iio subsystem and drivers, the rest · Maintainers:
Jiri Kosina, Jonathan Cameron, Srinivas Pandruvada, Linus Torvalds
From: Sanjay Chitroda <redacted> Introduce a local struct device pointer derived from &pdev->dev. This avoids repeated &pdev->dev usage and improves readability.
