Merge branch 'sch_api-style'
Alexander Aring says:
====================
net: sched: sch_api: fix coding style issues for extack
this patch prepares to handle extack for qdiscs and fixes checkpatch
issues.
There are a bunch of warnings issued by checkpatch which bothered me.
This first patchset is to get rid of those warnings to make way for
the next patchsets.
I plan to followup with qdiscs, classifiers and actions after this.
