Subject: [PATCH v2 12/39] drm/i915: gem: add kernel-doc description for some function parameters
Date:   Wed, 13 Jul 2022 09:12:00 +0100
Message-Id: <7940f1767c5c6f70196ae599448b87d75ba46834.1657699522.git.mchehab@kernel.org>

Precedence: bulk

There are some parameters missing at the kernel-doc markups on
some gem files. Some of those are trivial enough to be added.

Document them.
