Subject: [PATCH v3 08/20] drm/dp: Pass drm_dp_aux to drm_dp_link_train_clock_recovery_delay()
Date: Mon, 19 Apr 2021 18:55:10 -0400 [thread overview]
Message-ID: <20210419225523.184856-9-lyude@redhat.com> (raw)
In-Reply-To: <20210419225523.184856-1-lyude@redhat.com>
So that we can start using drm_dbg_*() in
drm_dp_link_train_clock_recovery_delay().
