The rcar_pcie_get_resources() is another misnomer with a side effect. The function does not only get resources, but also enables/disables bus clock. This is forgotten in the probe() function though and if anything in probe() fails after rcar_pcie_get_resources() is called, the bus clock are never disabled. This patch pulls the clock handling out of the rcar_pcie_get_resources() and enables clock after all the resources were requested. Moreover, this patch also always disables the clock in case of failure.
