[PATCH v2 9/9] iio: adc: ti-ads7950: Make use of the helper function dev_err_probe()

From: Cai Huoqing
Date: Mon Sep 27 2021 - 21:37:16 EST


When possible use dev_err_probe help to properly deal with the
PROBE_DEFER error, the benefit is that DEFER issue will be logged
in the devices_deferred debugfs file.
Using dev_err_probe() can reduce code size, and the error value
gets printed.
