drm/fb: remove unused function: drm_gem_fbdev_fb_create()
After migrating several drivers to the generic fbdev emulation there are no users left of drm_gem_fbdev_fb_create. Delete the function. Noticed that there was no callers while browsing around in the drm_fb* code. The code that referenced the function was removed by: commit13aff184ed
("drm/qxl: remove dead qxl fbdev emulation code") The actual use was removed by: commit26d4707d44
("drm/qxl: use generic fbdev emulation") v2: - Updated changelog based on feedback from Noralf Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Reviewed-by: Noralf Trønnes <noralf@tronnes.org> Cc: Gerd Hoffmann <kraxel@redhat.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20190721140610.GA20842@ravnborg.org
