Your patch claims to fix a bug, but the warning is a false positive. When we "goto queue_work;" then "ret = -EINVAL" so that means that we will not dereference "fw".
You should ignore false positive warnings.
We would apply the patch only if it made the code more readable but I do not think that is the case here. I do not really even see how the patch silences the false positive warning, but it may do...
Anyway, the point is: False positive. Ignore it.
