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

2024-03-01T12:41:47Z

commit dbcbfd662a725641d118fb3ae5ffb7be4e3d0fb0 upstream. 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.
