Subject: [PATCH net] net: dsa: mt7530: Use NULL instead of plain integer

We would be passing 0 instead of NULL as the rsp argument to
mt7530_fdb_cmd(), fix that.

Fixes: b8f126a8d543 ("net-next: dsa: add dsa support for Mediatek MT7530 switch")

BTW, does the part of the commit message should be updated with "passing
NULL instead of 0"?

I don't follow you, the commit message indicates what we were doing
which implies it was wrong and fixes it. Would you want me to reword
that part?
