There is no devmatch info in ig4_acpi.c at all for now. It can be added with placing of following line at the bottom of ig4_acpi.c
Along with checking of ACPI_ID_PROBE output instead of extra acpi_MatchHid() call, it will make devmatch happier.
ACPI_ID_PROBE returns a pointer to matched HID/CID in ig4iic_ids array in fouth parameter. It should be used instead of acpi_MatchHid() to detect "APMC0D0F" device.
