Subject: media: i2c: Use dev_err_probe() in ov8865 Author: Daniel Scally <[email protected]> Date: Tue Nov 23 01:00:15 2021 +0100 There is a chance that regulator_get() returns -EPROBE_DEFER, in which case printing an error message is undesirable. To avoid spurious messages in dmesg in the event that -EPROBE_DEFER is returned, use dev_err_probe() on error paths for regulator_get().
