Hi Sebastian,

I agree that the cited hash is a good commit to reference, but
I think the Fixes line has been mangled. A correct tag for that hash is:

Fixes: 73cfd947dbdb ("net: ethernet: mtk_eth_soc: ppe: prevent ppe update for non-mtk devices")

Also, please no blank line here, between the Fixes line and your Signed-off by.
