tty: serial: imx: Use platform_get_irq_optional() for optional IRQs
All i.MX SoCs except i.MX1 have ONLY one necessary IRQ, use platform_get_irq_optional() to get second/third IRQ which are optional to avoid below error message during probe: [ 0.726219] imx-uart 30860000.serial: IRQ index 1 not found [ 0.731329] imx-uart 30860000.serial: IRQ index 2 not found Fixes: 7723f4c5ecdb8d83 ("driver core: platform: Add an error message to platform_get_irq*()") Signed-off-by: Anson Huang <Anson.Huang@nxp.com> Link: https://lore.kernel.org/r/1570614559-11900-1-git-send-email-Anson.Huang@nxp.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
