Hi, Historically we did not trust PNP data regarding keyboard controllers on X86, but more and more boards get upset with us if they try to tell us that there is no keyboard controller and we still go and try to poke at where we think it might be. To work around this issue let's have a bit more faith in BIOS data, and if [lack] of PNP devices for mouse and keyboard matches whet firmware (basically ACPI FADT) tells us, let's abort i8042 probe. We add a new flag (enum) to x86_platform.legacy structure so we can distinguish between cases where platform/subarch never has 8042 (such as MID platform) and cases where firmware says that it is not there, so that i8042 driver can either abort immediately or go and check for presence of PNP devices. We also remove x86_platform.i8042_detect() as it is no longer used (platforms can set value of x86_platform.legacy.i8042 as needed in quirks). If you are OK with arch/x86 changes please apply together with the input part.
