Subject[PATCH] PCI: tegra194: Fix PM error handling in tegra_pcie_config_ep
Date
The pm_runtime_enable() will increase power disable depth.
if dw_pcie_ep_init() fails, we should use pm_runtime_disable()
to balance it pm_runtime_enable().
Add missing pm_runtime_disable() for tegra_pcie_config_ep()

Fixes: c57247f940e8 ("PCI: tegra: Add support for PCIe endpoint mode in Tegra194")
