[PATCH v3 03/37] drm/i915: gt: fix some Kernel-doc issues

From: Mauro Carvalho Chehab
Date: Fri Sep 09 2022 - 03:36:59 EST

There are several trivial warnings there, due to trivial things:
- lack of function name at the kerneldoc markup;
- undocumented structs with kernel-doc markups;
- wrong parameter syntax.

Fix such warnings:
