platform/x86: touchscreen_dmi: Consolidate Goodix upside-down touchscreen data

2024-02-19T11:42:58Z

Now that prefix matches for ACPI names are supported, the ts_dmi_data structs for "GDIX1001:00" and "GDIX1001:01" can be consolidated into a single match matching on "GDIX1001". For consistency also change gdix1002_00_upside_down_data to match.

platform/x86: touchscreen_dmi: Allow partial (prefix) matches for ACPI names

2024-02-19T11:42:45Z

On some devices the ACPI name of the touchscreen is e.g. either MSSL1680:00 or MSSL1680:01 depending on the BIOS version. This happens for example on the "Chuwi Hi8 Air" tablet where the initial commit's ts_data uses "MSSL1680:00" but the tablets from the github issue and linux-hardware.org probe linked below both use "MSSL1680:01". Replace the strcmp() match on ts_data->acpi_name with a strstarts() check to allow using a partial match on just the ACPI HID of "MSSL1680" and change the ts_data->acpi_name for the "Chuwi Hi8 Air" accordingly to fix the touchscreen not working on models where it is "MSSL1680:01". Note this drops the length check for I2C_NAME_SIZE. This never was necessary since the ACPI names used are never more then 11 chars and I2C_NAME_SIZE is 20 so the replaced strncmp() would always stop long before reaching I2C_NAME_SIZE.
