TinyUSB adds new warnings to the compilation process. Operations
inside of {} initializers get propagated to 'int' but get assigned
to uint8_t.
Add static casts to to uint8_t to avoid a bunch of warnings like this:
cores/arduino/Adafruit_TinyUSB_Core/Adafruit_USBD_CDC.cpp: In member function
'virtual uint16_t Adafruit_USBD_CDC::getDescriptor(uint8_t, uint8_t*, uint16_t)':
cores/arduino/Adafruit_TinyUSB_Core/tinyusb/src/device/usbd.h:172:74: warning:
narrowing conversion of '(((int)itfnum) + 1)' from 'int' to 'uint8_t
{aka unsigned char}' inside { } [-Wnarrowing]
5, TUSB_DESC_CS_INTERFACE, CDC_FUNC_DESC_CALL_MANAGEMENT, 0, (_itfnum) + 1,\
