clang static analyzer reports this problem
i2c-amd-mp2-plat.c:174:9: warning: Branch condition evaluates
to a garbage value
return err ? err : num;
^~~
err is not initialized, it depends on the being set in the
transfer loop which will not happen if num is 0. Surveying
other master_xfer() implementations show all handle a 0 num.
Because returning 0 is expected, initialize err to 0.
