From d28ea1fbbf437054ef339afec241019f2c4e2bb6 Mon Sep 17 00:00:00 2001 From: Manivannan Sadhasivam Date: Tue, 19 May 2020 23:44:16 +0530 Subject: net: qrtr: Fix passing invalid reference to qrtr_local_enqueue() 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().
