Subject: [PATCH 1/3] uio_pdrv_genirq: Remove warning when irq is not specified
Date: Wed, 1 Jul 2020 16:56:57 +0200 [thread overview]
Message-ID: <20200701145659.3978-2-esben@geanix.com> (raw)
In-Reply-To: <20200701145659.3978-1-esben@geanix.com>
Since e3a3c3a20555 ("UIO: fix uio_pdrv_genirq with device tree but no
interrupt"), the uio_pdrv_genirq has supported use without interrupt,
so the change in 7723f4c5ecdb ("driver core: platform: Add an error
message to") added false warnings for those cases.
Fixes: 7723f4c5ecdb ("driver core: platform: Add an error message to platform_get_irq*()")
