Convert the remaining fbdev drivers to use fbdev's helpers macros for struct fb_ops. Then push the current default code for file-I/O operations into a module and remove it as default. Each driver now selects the helpers its needs for file I/O and drawing to its framebuffer. If no helper has been set for an operation in struct fb_ops, the operation is unsupported. Once applied, fbdev drivers will not include unnecessary helper code. The helpers will also be more robust against mis-use. The first 2 patches are bug fixes. Patches 3 to 26 modify fbdev drivers to set up their fb_ops structures correctly and select the necessary helpers. Patches 27 and 28 do a few additional minor cleanups. Patches 29 to 32 move all helpers for struct fb_ops into modules and drop the default. Helpers also warn if they operate on the wrong type of framebuffer memory. Framebuffers in I/O memory and system memory can only be used with the correct helper functions.
