[PATCH 1/3] media: i2c: ov2685: propagate reset GPIO errors

[phucduc.bui@gmail.com]

From: bui duc phuc <phucduc.bui@gmail.com>

devm_gpiod_get_optional() may return -EPROBE_DEFER or other errors,
but ov2685_probe() currently converts them all to -EINVAL.

Use dev_err_probe() to propagate the original error from the reset GPIO
lookup.

Fixes: 0482fbb1c1cc ("media: i2c: ov2685: Make reset gpio optional")
Fixes: e3861d9118c8 ("media: ov2685: add support for OV2685 sensor")
