From 90ab44517ee1f9e5018b6c274b95219cf229e617 Mon Sep 17 00:00:00 2001 From: bui duc phuc Date: Wed, 9 Sep 2026 11:54:48 +0700 Subject: [PATCH] net: xilinx: axienet: Propagate errors from optional IRQ lookup platform_get_irq_optional() returns a positive IRQ number on success or a negative error code on failure. For an optional IRQ, -ENXIO indicates that no optional IRQ is available, while other errors should be propagated. Propagate all error codes returned by platform_get_irq_optional() other than -ENXIO. Another call to platform_get_irq_optional() in the same function already handles the return value this way. Apply the same error handling to this call site for consistency.
