====================
net: hns: fix the typo of hns

This series includes typo fixes which review by Andy, adding
the hns maintainer to MAINTAINERS, as below:

 > from Daode: adds the maintainer for hns driver;

 > from Daode: fix the typo of hns reviewed by Andy Shevchenko;

 > from Kejian: one remove redundant function and two fix to get
configuration from DT.

changlog:
 v2 -> v3:
  match all files in and below drivers/net/ethernet/hisilicon/

 v1 -> v2:
  fix the indentations reviewed by David.
====================
