Subject: [PATCH v7 8/9] iio: ssp_sensors: Use dev_err_probe
Date: Sun, 26 Apr 2026 14:47:09 +0530	[thread overview]
Message-ID: <20260426091710.3722035-9-sanjayembedded@gmail.com> (raw)
In-Reply-To: <20260426091710.3722035-1-sanjayembedded@gmail.com>

From: Sanjay Chitroda <sanjayembeddedse@gmail.com>

dev_err_probe() makes error code handling simpler and handle
deferred probe nicely (avoid spamming logs).

Signed-off-by: Sanjay Chitroda <sanjayembeddedse@gmail.com>
