Drop the unnecessary parentheses.

Question for DSA maintainers: shouldn't this be implemented in the
dsa_switch_ops phylink_validate callback, like it's done for other
dsa drivers?


Kind regards,
Niklas

Hi Niklas

qca8K is still using phylib, not phylink. So the validate callback
cannot be used.

Hi Xiaofei

What tree is this patch against? I don't think it is net-next. It
actually looks to be an old tree. Please rebase to David Millers
net-next. Patches to that tree are closed at the moment, due to the
merge window. You can post an RFC, or wait until it opens again.

Thanks
	Andrew

Hi Andrew

Thanks for your comments. I have sent a new patch based on net-next 
tree.

Thanks
Xiaofeis
