From cca0e54905259a456d97652d4f1e2fe8b188b6ad Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Tue, 25 Aug 2009 11:46:51 -0300 Subject: [PATCH] V4L/DVB (12520): sh-mobile-ceu-camera: do not wait for interrupt when releasing buffers Patch [PATCH] video: use videobuf_waiton() in sh_mobile_ceu free_buffer() was not quite correct. It closed a race, but introduced a potential lock-up, if for some reason an interrupt does not come. This has been observed in tests with tw9910. This patch safely dequeues buffers without waiting for their completion. It also moves a buffer state assignment under a spinlock to make it atomic with queuing of the buffer.
