Subject: rpmsg: glink: Initialize the "intent_req_comp" completion variable
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.
Fixes: 27b9c5b66b23 ("rpmsg: glink: Request for intents when unavailable")
