[PATCH net-next 0/2] team: change return value of init and getter in the team_option structure to void

[Zhengchao Shao]

Because the init and getter function always returns 0, so change return
value of init and getter in the team_option structure to void and remove
redundant code.

Reading this 5 times, I don't understand the sentence :/

Also, why you send 2 patchsets and 2 seperate patches, all for team? Why
don't you send it as one 6-patch patchset?
