From effcc625eb4ab3b10b4744237fd37e8f7dcd6511 Mon Sep 17 00:00:00 2001 From: Amitkumar Karwar Date: Wed, 28 Mar 2012 11:38:01 -0700 Subject: libertas: fix signedness bug in lbs_auth_to_authtype() Return type for lbs_auth_to_authtype() is changed from "u8" to "int" to return negative error code correctly. Also an error check is added in connect handler for invalid auth type. Reported-by: Dan Carpenter Signed-off-by: Amitkumar Karwar Signed-off-by: Kiran Divekar Signed-off-by: John W.

Upon switching to these channels the brcmsmac driver suspends the transmit dma fifos. This patch resumes them upon handing over the first received beacon to mac80211. This patch is to be applied to the stable tree for kernel versions 3.2 and 3.3.
