From: Kelvin Cao ENOTSUPP is not a SUSV4 error code, and the following checkpatch.pl warning will be given for new patches which still use ENOTSUPP. WARNING: ENOTSUPP is not a SUSV4 error code, prefer EOPNOTSUPP See the link below for the discussion. Link: https://lore.kernel.org/netdev/20200511165319.2251678-1-kuba(a)kernel.org/ Replace ENOTSUPP with EOPNOTSUPP to align with future patches which will be using EOPNOTSUPP.
