From b74d6e740be36d6d0c05f3386520fb44bae886b3 Mon Sep 17 00:00:00 2001 From: Amitkumar Karwar Date: Wed, 29 Jun 2016 17:32:40 +0530 Subject: [PATCH] mwifiex: fix scan_block flag handling scan_block flag is used to block scan operation when 4 way handshake is in progress. Sometimes it doesn't get cleared due to incomplete association. An example is assoc request/response is done, but add key operation get canceled in some corner cases. As a result, further association/scan operations are blocked. This patch fixes the problem by clearing scan_block flag.
