6.12-stable review patch. If anyone has any objections, please let me know. ------------------ From: Rosen Penev <[email protected]> [ Upstream commit ef19a9cf037957fe3a35df8355c76ff0a63a0436 ] Board files in arch/arm/plat-orion, arch/arm/mach-dove, arch/arm/mach-mv78xx0 and arch/arm/mach-orion5x still register the "sata_mv" device with two resources (IORESOURCE_MEM plus IORESOURCE_IRQ). Those devices are rejected with -EINVAL, so SATA no longer probes on legacy Marvell Orion/Kirkwood-style boards. Accept both 1 resource (DT, IRQ fetched via platform_get_irq()) and 2 resources (legacy, IRQ supplied as a second resource) so both probing paths work. Fixes: b3b2bec9646e ("ata: sata_mv: Fixes expected number of resources now IRQs are gone") Assisted-by: opencode:big-pickle Signed-off-by: Rosen Penev <[email protected]> Signed-off-by: Damien Le Moal <[email protected]> Signed-off-by: Sasha Levin <[email protected]> --- drivers/ata/sata_mv.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/ata/sata_mv.c b/drivers/ata/sata_mv.c index 05c905827dc5c..40fdc422940dd 100644 --- a/drivers/ata/sata_mv.c +++ b/drivers/ata/sata_mv.c @@ -4026,7 +4026,7 @@ static int mv_platform_probe(struct platform_device *pdev) /* * Simple resource validation .. */ - if (unlikely(pdev->num_resources != 1)) { + if (unlikely(pdev->num_resources != 1 && pdev->num_resources != 2)) { dev_err(&pdev->dev, "invalid number of resources\n"); return -EINVAL; } -- 2.53.0
