From 48b63b6908a10add9ee383c7db24c37f99e5d324 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 3 Jan 2011 13:49:43 +0000 Subject: [PATCH] video/msm_fb: use system_wq instead of dedicated workqueues With cmwq, there's no reason to use separate workqueues. Drop msmfb_info->resume_workqueue and use system_wq instead.
