Framebuffer devices that are registered by DRM drivers for fbdev emulation have a "drmfb" suffix in their name. But makes them to be quite confusing for drivers that already have "drm" in their name: $ cat /proc/fb 0 rockchipdrmdrmfb $ cat /proc/fb 0 simpledrmdrmfb Also, there isn't a lot of value in adding these "drmfb" suffices to their names, since users shouldn't really care if the FB devices were registered by a real fbdev driver or a DRM driver using the fbdev emulation. What programs should be interested about is if there's a DRM device, and there are better ways to query that info than reading this procfs entry. So let's just remove the suffix, which leads to much better device names: $ cat /proc/fb 0 rockchipdrm $ cat /proc/fb 0 simpledrm Suggested-by: Thomas Zimmermann <tzimmermann@suse.de> Signed-off-by: Javier Martinez Canillas <javierm@redhat.com> --- Changes in v2: - Just remove the "drmfb" suffix instead of using a different one (tzimmermann). drivers/gpu/drm/drm_fb_helper.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
