From a7b134a7676edf68d05fe44f0a045c14cadd66b2 Mon Sep 17 00:00:00 2001 From: Hante Meuleman Date: Fri, 6 Feb 2015 18:36:46 +0100 Subject: [PATCH] brcmfmac: Dont sleep when ctrl frames to transmit. The SDIO watchdog will put the device in sleep mode when there is no activity for some time and nothing to do anymore. This check is incomplete and should also check if there is a control frame to transmit.
