[PATCH v1 2/7] pps: clients: gpio: Use dev_err_probe() to avoid log noise

From: Andy Shevchenko
Date: Tue Feb 16 2021 - 06:36:20 EST


When GPIO APIs return -EPROBE_DEFER there is no need to print the message,
especially taking into consideration that it may repeat several times.
Use dev_err_probe() to avoid log noise in such cases.
