Subject: [PATCH] platform/surface: aggregator: Do not mark interrupt as shared
Date: Wed, 5 May 2021 15:36:35 +0200 [thread overview]
Message-ID: <20210505133635.1499703-1-luzmaximilian@gmail.com> (raw)
Having both IRQF_NO_AUTOEN and IRQF_SHARED set causes
request_threaded_irq() to return with -EINVAL (see comment in flag
validation in that function). As the interrupt is currently not shared
between multiple devices, drop the IRQF_SHARED flag.
Fixes: 507cf5a2f1e2 ("platform/surface: aggregator: move to use request_irq by IRQF_NO_AUTOEN flag")
