drm/fb_helper: Create wrappers for blit, copyarea and fillrect funcs
drm drivers that emulate fbdev populate their fb_fillrect, fb_copyarea and fb_imageblit fb_ops with the help of cfb_* or sys_* fbdev core helper functions. Create drm_fb_helper functions that wrap 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: - Fixed 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>
