drm/fb_helper: Create wrappers for fb_sys_read/write funcs
Some drm drivers populate their fb_ops with fb_sys_read/write fb sysfs ops. Create a drm_fb_helper function that wraps around these calls. This is part of an effort to prevent drm drivers from calling fbdev functions directly, in order to make fbdev emulation a top level drm option. v3: - Fix kerneldoc errors v2: - Added kerneldocs - Follow the drm way of aligning of arguments in func definitions - Remove unnecessary checks for non NULL fb_info Signed-off-by: Archit Taneja <architt@codeaurora.org> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
