Hello, this is the fourth version of the mem-to-mem device framework. Changes in v4: - v4l2_m2m_poll() now also reports POLLOUT | POLLWRNORM when an output buffer is ready to be dequeued - more cleaning up, addressing most of the comments to v3 Vaibhav: your clean-up patch didn't apply after my changes. I incorporated most of your clean-up changes. If you prefer it to be separate, we will have to prepare another one somehow. Also, sorry, but I cannot agree with changing unsigned types into u32, I do not see any reason to use fixed-width types there. This series contains: [PATCH v4 1/2] v4l: Add memory-to-memory device helper framework for videobuf. [PATCH v4 2/2] v4l: Add a mem-to-mem videobuf framework test device.
