Subject: [PATCH 1/2] thermal/drivers/rcar_gen3: Handle -ENXIO from optional IRQ lookup
Date: Fri, 7 Aug 2026 16:30:57 +0700 [thread overview]
Message-ID: <20260807093058.42840-1-phucduc.bui@gmail.com> (raw)
From: bui duc phuc <phucduc.bui@gmail.com>
platform_get_irq_optional() returns -ENXIO when the optional IRQ is not
specified. Treat -ENXIO as a valid absence of an optional IRQ, while
propagating other errors.
