[PATCH 05/14] ASoC: rockchip: rockchip_i2s: Propagate -EPROBE_DEFER from devm_pinctrl_get()

[phucduc.bui at gmail.com]

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

Return -EPROBE_DEFER from devm_pinctrl_get() instead of ignoring it and
continuing probe. This allows the driver to be reprobed once the
pinctrl provider becomes available.
