Hi All,
Here is an attempt to fix an issue which is causing I2C-HID touchpads /
touchscreens to not work on various recent Intel CPU using Lenovo Ideapad
laptop models. There are quite a few reports about this and I think I've
finally figured out what is going on here. See the patch for details.
Note this is just a RFC for now, with as purpose to gather some feedback,
specifically feedback on if the solution I came up with to just reject all
_CSR returned PCI IOMEM regions with a base-address of 0 is acceptable.
This is a RFC becase I'm waiting to hear back from the reporters to see if
the patch actually fixes things.
Regards,
Hans
