Subject: [PATCH 07/11] wil6210: properly initialize discovery_expired_work
Date: Sun,  8 Sep 2019 11:32:51 +0300
Message-ID: <1567931575-27984-8-git-send-email-merez@codeaurora.org> (raw)
In-Reply-To: <1567931575-27984-1-git-send-email-merez@codeaurora.org>

From: Dedy Lansky <dlansky@codeaurora.org>

Upon driver rmmod, cancel_work_sync() can be invoked on
p2p.discovery_expired_work before this work struct was initialized.
This causes a WARN_ON with newer kernel version.

Add initialization of discovery_expired_work inside wil_vif_init().
