From a034d1b76b173b37f9a3646aa8f50a2c14a0f3ea Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Fri, 11 Jul 2008 20:59:34 -0300 Subject: V4L/DVB (8338): soc_camera: Move spinlocks This patch moves the spinlock handling from soc_camera.c to the actual camera host driver. The spinlock_alloc/free callbacks are replaced with code in init_videobuf(). So far all camera host drivers implement their own spinlock_alloc/free methods anyway, and videobuf_queue_core_init() BUGs on a NULL spinlock argument, so, new camera host drivers will not forget to provide a spinlock when initialising their videobuf queues.
