5.4-stable review patch. If anyone has any objections, please let me know.

From: Krzysztof Kozlowski krzysztof.kozlowski@linaro.org
commit 92bac7d4de9c07933f6b76d8f1c7f8240f911f4f upstream.
Driver in the probe enables wakeup source conditionally, so the cleanup path should do the same - do not release the wakeup source memory if it was not allocated.
