serial: 8250-mtk: Use platform_get_irq_optional() for optional irq
commit5.4-rM2-2.2.x-imx-squashedeb9c1a41ea
upstream. As platform_get_irq() now prints an error when the interrupt does not exist, this warnings are printed on bananapi-r2: [ 4.935780] mt6577-uart 11004000.serial: IRQ index 1 not found [ 4.962589] 11002000.serial: ttyS1 at MMIO 0x11002000 (irq = 202, base_baud = 1625000) is a ST16650V2 [ 4.972127] mt6577-uart 11002000.serial: IRQ index 1 not found [ 4.998927] 11003000.serial: ttyS2 at MMIO 0x11003000 (irq = 203, base_baud = 1625000) is a ST16650V2 [ 5.008474] mt6577-uart 11003000.serial: IRQ index 1 not found Fix this by calling platform_get_irq_optional() instead. now it looks like this: [ 4.872751] Serial: 8250/16550 driver, 4 ports, IRQ sharing disabled Fixes:7723f4c5ec
