This is a note to let you know that I have just added a patch titled rtlwifi: rtl8821ae: Fix an expression that is always false to the linux-3.19.y-queue branch of the 3.19.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-3.19.y-queue This patch is scheduled to be released in version 3.19.8-ckt8. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.19.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From 48ed7e423dfee1a159cfebd22449ce1bddc0dfe0 Mon Sep 17 00:00:00 2001 From: Larry Finger <Larry.Finger@lwfinger.net> Date: Wed, 8 Jul 2015 10:18:50 -0500 Subject: rtlwifi: rtl8821ae: Fix an expression that is always false commit 251086f588720277a6f5782020a648ce32c4e00b upstream. In routine _rtl8821ae_set_media_status(), an incorrect mask results in a test for AP status to always be false. Similar bugs were fixed in rtl8192cu and rtl8192de, but this instance was missed at that time.
