From dd669e907cbe1cf33f9cbbff79af2b5c271cdd89 Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Mon, 24 Dec 2012 09:31:33 -0300 Subject: [media] soc-camera: remove struct soc_camera_device::video_lock Currently soc-camera has a per-device node lock, used for video operations and a per-host lock for code paths, modifying host's pipeline. Manipulating the two locks increases complexity and doesn't bring any advantages. This patch removes the per-device lock and uses the per-host lock for all operations.
