Commit 757926247836 ("net: stmmac: add flexible PPS to dwmac
4.10a") was intended to modify the struct dwmac410_ops, but it got
somehow badly merged and modified the struct dwmac4_ops.

Revert the modification in struct dwmac4_ops and re-apply it
properly in struct dwmac410_ops.

I don't think extension of dwmac410_ops should be backported to stable.
It's a new feature and should go into net-next like any other.
The fix that could be backported is reverting the unintentional change
of dwmac4.

Cheers,
Ahmad

Applied, and queued for 5.9 (all other 5.5+ branches are EOL by now).

Thanks!
