From 564db8b8da8d5293424406114244c24ef947dd1c Mon Sep 17 00:00:00 2001 From: bui duc phuc Date: Thu, 6 Aug 2026 13:10:45 +0700 Subject: [PATCH] ASoC: dwc: Propagate -EPROBE_DEFER from IRQ lookup platform_get_irq_optional() never returns 0. It returns a positive IRQ number on success or a negative error code on failure. 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.
