From 39b553dbb4a75debf814a261e58f09347eef337f Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Thu, 4 Apr 2013 08:56:00 -0300 Subject: [PATCH] [media] pxa-camera: move interface activation and deactivation to clock callbacks When adding and removing a client, the pxa-camera driver only activates and deactivates its camera interface respectively, which doesn't include any client-specific actions. Move this functionality into .clock_start() and .clock_stop() callbacks.
