Subject: [PATCH resend v1 2/7] pps: clients: gpio: Use dev_err_probe() to avoid log noise
Date:   Tue,  9 Mar 2021 13:23:58 +0200
Message-Id: <20210309112403.36633-2-andriy.shevchenko@linux.intel.com>

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.
