Cannot compile for ATSAMD21 board, SERIAL_TX_BUFFER_SIZE not defined

[aaronw2]

I'm trying to build this for the Adafruit Trinket M0 board but am getting the following errors.

/home/aaronw/Arduino/libraries/FUSB302_PD_UFP_sink/src/PD_UFP_Log.cpp:96: warning: "PSTR" redefined
96 | #define PSTR(str) str
… | ^~~~~~~~~~~~~~~~~~~~~

/home/aaronw/Arduino/libraries/FUSB302_PD_UFP_sink/src/PD_UFP_Log.cpp:236:33: error: 'buf' was not declared in this scope

Just open the file PD_UFP_Log.cpp and define the macro.
#define SERIAL_TX_BUFFER_SIZE (Any size for e.g:- 1024)
