From dcd5c79c9a3a7ac08bdce089fec810677ce6efe8 Mon Sep 17 00:00:00 2001 From: Bing Zhao Date: Fri, 19 Oct 2012 19:01:59 -0700 Subject: [PATCH] mwifiex: return -EBUSY if specific scan request cannot be honored Previous patch "mwifiex: return -EBUSY if scan request cannot.." corrected regular scan request only. There is another case for specific scan that needs the same handling. Also, removed !req_ssid check as it has already been validated by caller.
