Remove all unused interfaces that used to implement the functionality of pre_switch and post_switch. For pre_switch, remove vga_switcheroo_client_fb_set(). This further allows for removing all symbols and data structures that refer to fbdev; such as fb_info and fb_switch_outputs(). For post_switch, remove the reprobe callback from the client ops. v2: - move changes to fbcon and drivers into other patches Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Maxime Ripard <mripard@kernel.org> Acked-by: Helge Deller <deller@gmx.de> Link: https://patch.msgid.link/20260709092215.168172-8-tzimmermann@suse.de
