Subject: [PATCH] drm/i915/dp: Fix link compute m_n calc for DSC
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit
Fix the intel_link_compute_m_n in case of display stream
compression. This patch passes the compressed_bpp to
intel_link_compute_m_n if compression is enabled.
Fixes: a4a157777c80 ("drm/i915/dp: Compute DSC pipe config in atomic check")
