Subject: [PATCH] iio: ssp_sensors: fix error code in ssp_print_mcu_debug()
Date: Tue, 14 Sep 2021 13:53:33 +0300 [thread overview]
Message-ID: <20210914105333.GA11657@kili> (raw)
The ssp_print_mcu_debug() function should return negative error codes on
error. Returning "length" is meaningless. This change does not affect
runtime because the callers only care about zero/non-zero.
Reported-by: Jonathan Cameron <jic23@kernel.org>
Fixes: 50dd64d57eee ("iio: common: ssp_sensors: Add sensorhub driver")
