From: Luciano Coelho Date: Wed, 6 May 2015 07:45:42 +0000 (+0300) Subject: iwlwifi: mvm: fix the net-detect SSIDs report order X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ae90c2e5784b465d903106d833afab4f3e139d80;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git iwlwifi: mvm: fix the net-detect SSIDs report order After the scan refactor, the order of the SSIDs passed to the firmware in all scans (including net-detect) are inverted. This was causing the reporting code to use the wrong SSIDs. To fix this, invert the array index when accessing the saved match SSIDs to report the wake-up.
