Subject: [PATCH v8 05/12] iio: ssp_sensors: use local struct device
Date: Fri, 15 May 2026 23:10:10 +0530 [thread overview]
Message-ID: <20260515174017.3962168-6-sanjayembedded@gmail.com> (raw)
In-Reply-To: <20260515174017.3962168-1-sanjayembedded@gmail.com>
From: Sanjay Chitroda <sanjayembeddedse@gmail.com>
Introduce a struct device *dev derived from &spi->dev to improve
readability and drop redundant "Probe failed!" log in probe path.
Signed-off-by: Sanjay Chitroda <sanjayembeddedse@gmail.com>
---
Changes in v8:
- Following input from Andy and Jonathan don't mix variable reorder
with new variable addition and drop redundant log
- v7 change: https://lore.kernel.org/all/20260426091710.3722035-6-sanjayembedded@gmail.com/
