[PATCH 4.19 08/95] net: qrtr: Fix passing invalid reference to qrtr_local_enqueue()

[Greg Kroah-Hartman]

From: Manivannan Sadhasivam <manivannan.sadhasi...@linaro.org>

[ Upstream commit d28ea1fbbf437054ef339afec241019f2c4e2bb6 ]

Once the traversal of the list is completed with list_for_each_entry(),
the iterator (node) will point to an invalid object. So passing this to
qrtr_local_enqueue() which is outside of the iterator block is erroneous
eventhough the object is not used.

So fix this by passing NULL to qrtr_local_enqueue().
