[PATCH 11/14] ASoC: rockchip: rockchip_sai: Propagate -EPROBE_DEFER from IRQ lookup

[phucduc.bui at gmail.com]

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

Return -EPROBE_DEFER from platform_get_irq_optional() so the driver is
re-probed when the interrupt resource becomes available instead of
continuing probe without an IRQ.
