drm/fb-helper: Rename dirty worker to damage worker

2020-11-24T08:27:55Z

The dirty worker handles all damage updates, instead of just calling the framebuffer's dirty callback. Rename it to damage worker. Also rename related variables accordingly. No functional changes are made.

drm: Don't return 0 from a void drm_fbdev_generic_setup

drm/fb-helper: Remove return value from drm_fbdev_generic_setup()

2020-04-08T14:27:08Z

Generic fbdev emulation is a DRM client. Drivers should invoke the setup function, but not depend on its success. Hence remove the return value. v3: * document stricter requirements for call sequence v2: * warn if fbdev device has not been registered yet * document the new behavior * convert the existing warning to the new dev_ interface Signed-off-by: Thomas Zimmermann Reviewed-by: Sam Ravnborg Reviewed-by: Noralf Trønnes Acked-by: Sam Ravnborg Acked-by: Gerd Hoffmann Link: https://patchwork.freedesktop.org/patch/msgid/20200408082641.590-11-tzimmermann@suse.de

drm/fb-helper: Remove drm_fb_helper add, add_all and remove connector functions

drm_fb_helper_single_add_all_connectors(), drm_fb_helper_add_one_connector() and drm_fb_helper_remove_one_connector() don't keep an array of connectors anymore and are just dummy. Now we have no callers to these functions hence remove them.

drm/fb-helper: unexport drm_fb_helper_generic_probe

2019-11-13T12:06:27Z

Not sure we don't yet have this as a patch somewhere ... Motivation is that the automatic lifetime management of the generic fbdev code is quite tricky, and it'll get even more tricky. Allowing drivers to just use the fb_probe looks like a recipe for disaster.
