Subject: [PATCH v8 10/12] iio: ssp_sensors: Use dev_err_probe()
Date: Fri, 15 May 2026 23:10:15 +0530	[thread overview]
Message-ID: <20260515174017.3962168-11-sanjayembedded@gmail.com> (raw)
In-Reply-To: <20260515174017.3962168-1-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).
