Subject: [Intel-gfx] [PATCH] drm/i915/mst: Set intel_dp_set_m_n() for MST slaves
Date: Mon, 10 Feb 2020 10:40:57 -0800 [thread overview]
Message-ID: <20200210184057.296698-1-jose.souza@intel.com> (raw)
Commit 1c9d2eb24153 ("drm/i915: move intel_dp_set_m_n() to encoder for
DDI platforms") moved the intel_dp_set_m_n() from hsw_crtc_enable()
to intel_ddi_pre_enable_dp() but it missed add it to
intel_mst_pre_enable_dp() causing MST slaves to not work.
Fixes: 1c9d2eb24153 ("drm/i915: move intel_dp_set_m_n() to encoder for DDI platforms")
