4.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: Bjorn Helgaas <bhelgaas@xxxxxxxxxx>
commit 8dd99bca7bfa4b62753b556c45d26f45ec9da6e6 upstream.
The tegra_pcie_phy_disable() path called pads_writel() with arguments in
the wrong order. Swap them to be the "value, offset" order expected by
pads_writel().
Fixes: 6fe7c187e026 ("PCI: tegra: Support per-lane PHYs")
