uio_pdrv_genirq: Remove warning when irq is not specified
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*()") Signed-off-by: Esben Haabendal <esben@geanix.com> Cc: stable@vger.kernel.org Link: https://lore.kernel.org/r/20200701145659.3978-2-esben@geanix.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
