Subject: [PATCH v3] x86/resctrl: Fix kernel-doc in internal.h

Add description of undocumented parameters. Issues detected by
scripts/kernel-doc.

Signed-off-by: Fabio M. De Francesco <[email protected]>
---

v2->v3: Fix typo. Inherit the descriptions of membw and mbm_width from
commit
https://lore.kernel.org/lkml/[email protected]/
to make it easier to merge both patches.
v1->v2: According to a first review by Reinette Chartre, remove changes
unrelated to the subject of this patch and modify the descriptions of
two parameters.

This hunk continues to be whitespace broken. You are adding tabs when
existing comments use spaces. Please ensure that your changes fit with
