Merge branch 'wireguard-fixes'
Jason A. Donenfeld says:
====================
wireguard fixes for 5.7-rc4
This series contains two fixes and a cleanup for wireguard:
1) Removal of a spurious newline, from Sultan Alsawaf.
2) Fix for a memory leak in an error path, in which memory allocated
prior to the error wasn't freed, reported by Sultan Alsawaf.
3) Fix to ECN support to use RFC6040 properly like all the other tunnel
drivers, from Toke Høiland-Jørgensen.
