From a21fc2f5bef9031d6c7ace224c7061b9e53596e4 Mon Sep 17 00:00:00 2001 From: Malcolm Priestley Date: Fri, 27 Sep 2013 16:55:45 +0100 Subject: [PATCH] staging: vt6656: covert RXvMngWorkItem to work queue Tasklet to workqueue. RxMngWorkItem -> rx_mng_work_item Reduce atomic area of driver and dependency on system timer.
