Subject: [PATCH 1/3] platform/x86: hp: hp_accel: Propagate errors from optional IRQ lookup
Date: Mon, 10 Aug 2026 12:26:23 +0700 [thread overview]
Message-ID: <20260810052625.27614-1-phucduc.bui@gmail.com> (raw)
From: bui duc phuc <phucduc.bui@gmail.com>
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.
