[PATCH 4.14 102/178] rpmsg: glink: Initialize the "intent_req_comp" completion variable

From: Greg Kroah-Hartman
Date: Mon Dec 18 2017 - 11:15:26 EST

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


From: Arun Kumar Neelakantam <aneela@xxxxxxxxxxxxxx>

[ Upstream commit 2394facb17bcace4b3c19b50202177a5d8903b64 ]

The "intent_req_comp" variable is used without initialization which
results in NULL pointer dereference in qcom_glink_request_intent().

we need to initialize the completion variable before using it.
