The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will be merged to the tty-next branch sometime soon, after it passes testing, and the merge window is open. If you have any questions about this process, please let me know. >From eb9c1a41ea1234907615fe47d6e47db8352d744b Mon Sep 17 00:00:00 2001 From: Frank Wunderlich Date: Sun, 27 Oct 2019 07:21:17 +0100 Subject: serial: 8250-mtk: Use platform_get_irq_optional() for optional irq 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: 7723f4c5ecdb8d83 ("driver core: platform: Add an error message to platform_get_irq*()") Signed-off-by: Frank Wunderlich Cc: stable Link: https://lore.kernel.org/r/20191027062117.20389-1-frank-w@public-files.de Signed-off-by: Greg Kroah-Hartman --- drivers/tty/serial/8250/8250_mtk.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/tty/serial/8250/8250_mtk.c b/drivers/tty/serial/8250/8250_mtk.c index b411ba4eb5e9..4d067f515f74 100644 --- a/drivers/tty/serial/8250/8250_mtk.c +++ b/drivers/tty/serial/8250/8250_mtk.c @@ -544,7 +544,7 @@ static int mtk8250_probe(struct platform_device *pdev) pm_runtime_set_active(&pdev->dev); pm_runtime_enable(&pdev->dev); - data->rx_wakeup_irq = platform_get_irq(pdev, 1); + data->rx_wakeup_irq = platform_get_irq_optional(pdev, 1); return 0; } -- 2.23.0
