Previously, `riic_init_hw()` used `riic->adapter.dev` in error reporting. Since this function is invoked during the probe phase, the I2C adapter is not yet initialized, leading to `(null) ...` being printed in error messages. This patch fixes the issue by consistently using the local `dev` pointer, which points to `riic->adapter.dev.parent`. Additionally, replace `dev_err()` with `dev_err_probe()` throughout `riic_init_hw()` for consistency.
