Subject: [PATCH] usb: chipidea: ci_hdrc_imx: Propagate -EPROBE_DEFER from IRQ lookup
Date: Thu, 6 Aug 2026 13:52:54 +0700 [thread overview]
Message-ID: <20260806065254.28204-1-phucduc.bui@gmail.com> (raw)
From: bui duc phuc <phucduc.bui@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.
