Compiler error:

...\cores\nRF5\TinyUSB\Adafruit_TinyUSB_ArduinoCore\Adafruit_USBD_Device.cpp:
    In function 'int strcpy_utf16(const char*, uint16_t*, int)':
...\cores\nRF5\TinyUSB\Adafruit_TinyUSB_ArduinoCore\Adafruit_USBD_Device.cpp:294:17:
    warning: 'codepoint' may be used uninitialized in this function [-Wmaybe-uninitialized]
       codepoint -= 0x10000;
       ~~~~~~~~~~^~~~~~~~~~

This is caused by the variable 'codepoint' not being initialized in the error path.
