From 707bcf326bd50c875d82bd2e7c31dcfb92b7e813 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Fri, 24 Dec 2010 16:14:20 +0100 Subject: media/video: explicitly flush request_module work Video drivers request submodules using a work during probe and calls flush_scheduled_work() on exit to make sure the work is complete before being unloaded. This patch makes these drivers flush the work directly instead of using flush_scheduled_work(). While at it, relocate request_submodules() call in saa7134_initdev() right right before successful return as in other drivers to avoid failing after the work is scheduled and returning failure without the work still active. This is in preparation for the deprecation of flush_scheduled_work().
