Subject: [PATCH v3 24/29] staging: wilc1000: remove p2p related static variables to wilc_vif struct
Date:   Tue, 25 Sep 2018 11:53:39 +0530
Message-ID: <1537856624-22157-25-git-send-email-ajay.kathat@microchip.com>

Precedence: bulk

Avoid use of static variable and move them as part of private
data(wilc_priv) struct.
