Subject: [PATCH v3] x86/resctrl: Fix kernel-doc in internal.h
Date:   Wed, 16 Jun 2021 20:43:30 +0200
Message-Id: <20210616184330.13301-1-fmdefrancesco@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

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

Signed-off-by: Fabio M. De Francesco <fmdefrancesco@gmail.com>

v2->v3: Fix typo. Inherit the descriptions of membw and mbm_width from
commit
https://lore.kernel.org/lkml/20210614200941.12383-2-james.morse@arm.com/
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.
