Although not technically necessary because imx-media has only a maximum of 8 video devices, and once setup the video device lists are static, in anticipation of moving control ineritance to v4l2-core, make the vdev lists more generic by converting to dynamic list_head's. After doing that, 'struct imx_media_pad' is now just a list_head of video devices reachable from a pad. Allocate an array of list_head's, one list_head for each pad, and attach that array to sd->host_priv. An entry in the pad lists is of type 'struct imx_media_pad_vdev', and points to a video device from the master list.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
