drm/fb_helper: Create a wrapper for unlink_framebuffer
Some drm drivers call unlink_framebuffer. 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. v2: - Added kerneldocs - Added a check for non-NULL fb_helper before proceeding. This will make the helpers work when we have a module param for fbdev emulation Signed-off-by: Archit Taneja <architt@codeaurora.org> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
