From cbb1a82e5608fd6511940d27c231f0f4e2495b04 Mon Sep 17 00:00:00 2001 From: Archit Taneja Date: Fri, 31 Jul 2015 16:21:41 +0530 Subject: 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 Signed-off-by: Daniel Vetter --- include/drm/drm_fb_helper.h | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'include/drm/drm_fb_helper.h') diff --git a/include/drm/drm_fb_helper.h b/include/drm/drm_fb_helper.h index 4c908370a61e..fc123685baf4 100644 --- a/include/drm/drm_fb_helper.h +++ b/include/drm/drm_fb_helper.h @@ -147,6 +147,11 @@ void drm_fb_helper_fill_fix(struct fb_info *info, uint32_t pitch, void drm_fb_helper_unlink_fbi(struct drm_fb_helper *fb_helper); +ssize_t drm_fb_helper_sys_read(struct fb_info *info, char __user *buf, + size_t count, loff_t *ppos); +ssize_t drm_fb_helper_sys_write(struct fb_info *info, const char __user *buf, + size_t count, loff_t *ppos); + int drm_fb_helper_setcmap(struct fb_cmap *cmap, struct fb_info *info); int drm_fb_helper_hotplug_event(struct drm_fb_helper *fb_helper); -- cgit v1.2.3
