Jacopo Mondi	d619dd9a3d	media: v4l2-isp: Rename block_info to block_type_info ... The v4l2_isp_params_block_info structure contains validation information that apply to a block -type- and not only to a specific ISP block implementation. Clarify this by renaming v4l2_isp_params_block_info in v4l2_isp_params_block_type_info and update the documentation and the users of v4l2-isp accordingly.

Jacopo Mondi	3cb6de6faf	media: v4l2-core: Introduce v4l2-isp.c ... Add to the V4L2 framework helper functions to support drivers when validating a buffer of V4L2 ISP parameters. Driver shall use v4l2_isp_params_validate_buffer_size() to verify the size correctness of the data received from userspace, and after having copied the data to a kernel-only memory location, complete the validation by calling v4l2_isp_params_validate_buffer().
