[PATCH 4.4 71/86] mwifiex: fix p2p device doesnt find in scan problem

From: Greg Kroah-Hartman
Date: Thu Nov 29 2018 - 09:19:36 EST

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


From: Karthik D A <karthida@xxxxxxxxxxx>

commit 3d8bd85c2c9e47ed2c82348aa5b6029ed48376ae upstream.

Marvell p2p device disappears from the list of p2p peers on the other
p2p device after disconnection.

It happens due to a bug in driver. When interface is changed from p2p
to station, certain variables(bss_type, bss_role etc.) aren't correctly
updated. This patch corrects them to fix the issue.
