Subject: [PATCH] platform: goldfish: pipe: switch to platform_get_irq
Date: Sun, 29 Dec 2019 08:34:50 +0000 [thread overview]
Message-ID: <20191229083450.8178-1-tiny.windzz@gmail.com> (raw)
platform_get_resource(pdev, IORESOURCE_IRQ) is not recommended for
requesting IRQ's resources, as they can be not ready yet. Using
platform_get_irq() instead is preferred for getting IRQ even if it
was not retrieved earlier.
