From: Lukas Wunner <lukas@wunner.de> commit 5ef76dac0f2c26aeae4ee79eb830280f16d5aceb upstream. If the calls to devm_platform_ioremap_resource(), irq_of_parse_and_map() or devm_request_irq() fail on probe of the ST SSC4 SPI driver, the runtime PM disable depth is incremented even though it was not decremented before. Fix it.
