Subject: PCI: rockchip: Fix negotiated lanes calculation
From: Shawn Lin <[email protected]>
commit 45e9320f3a4ef9588ee50a2eb1891c4bfdbb07df upstream.
The calculation of negotiated lanes is wrong: it should be shifted by PCIE_CORE_PL_CONF_LANE_SHIFT, but it is shifted by PCIE_CORE_PL_CONF_LANE_MASK instead. Let's fix it.
