From 507daea2276677785ba8096d90b9e8049632fc46 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Wed, 9 Mar 2011 19:54:28 +0100 Subject: [PATCH] dac960: Convert to bdops->check_events() Convert from ->media_changed() to ->check_events(). DAC960 media change notification seems to be one way (once set, never cleared) and will generate spurious events when polled once the condition triggers.
