Check\nwith fbcon if the mode change is possible, update hardware state and\nfinally update fbcon. Update all callers.\n\nOnly the FBIOPUT_VSCREENINFO ioctl currently does all steps. Other\nmode-changes callers in sysfs and driver code are missing fbcon-related\nsteps.\n\nWith the new helper, ps3fb and sh_mobile_lcdcfb no longer maintain\nfbcon state themselves."
