Subject: Re: [PATCH net-next] net: dsa: drop pointless static qualifier in
 ar9331_sw_mbus_init

Hi Mao,
the commit title should be something of the form
  net: dsa: qca: ar9331: drop pointless static qualifier
or
  net: dsa: ar9331: drop pointless static qualifier

If it begins only with
  net: dsa:
then it makes people think you are changing stuff in main dsa code.

Marek
