[ Upstream commit b59b86c5d08be7d761c04affcbcec8184738c200 ]
At probe error path, the firmware loading work may have already been queued. In such a case, it will try to access memory allocated by the probe function, which is about to be released. In such paths, wait for the firmware worker to finish before releasing memory.
