This patch checks the state of the buffer when calling .buf_init() method. This is needed for the USERPTR buffer type, because in that case .buf_init() is called every time a buffer is queued, and not only once during the preparation stage, like in the MMAP case. Without this check buffers get initialised repeatedly, which also leads to the allocation of new DMA descriptors, of which there is only a final relatively small number available. Both MMAP and USERPTR methods were successfully tested.

If the camera was set to output formats like RGB565 YUYV or SBGGR10, the resulting image was scrambled due to erroneous interpretations of horizontal parameter's units. This patch in fourcc_to_ipu_pix, eliminate also the pixel formats mappings that, first are not used within mainline code and second, standing at the datasheets, they will not work properly: The IPU internal bus support only the following data formatting (44.1.1.3 Data Flows and Formats): 1 YUV 4:4:4 or RGB-8 bits per color component 2 YUV 4:4:4 or RGB-10 bits per color component 3 Generic data (from sensor to the system memory only) And format conversions are done: - from memory: unpacking from other formats to IPU supported ones - to memory: packing in the inverse order. So, assigning a packing/unpacking strategy to the IPU for those formats will produce a packing to memory and not the inverse.
