Just before where you add the new case, there is:
/* fallthrough */
case TP_HKEY_EV_KEY_NUMLOCK:
case TP_HKEY_EV_KEY_FN:
/* key press events, we just ignore them as long as the EC
* is still reporting them in the normal keyboard stream */
*send_acpi_ev = false;
*ignore_acpi_ev = true;
return true;
You should just be able to do:
case TP_HKEY_EV_KEY_FN:
+ case TP_HKEY_EV_KEY_FN_ESC:
Rather than duplicating the same logic below a new case block.
