[PATCH 1/2] bus: bt1-apb: Don't print error on -EPROBE_DEFER

From: Serge Semin
Date: Fri Jun 10 2022 - 04:01:21 EST


The Baikal-T1 APB bus driver correctly handles the deferred probe
situation, but still pollutes the system log with a misleading error
message. Let's fix that by using the dev_err_probe() method to print the
log message in case of the clocks/resets request errors.
