Geert Uytterhoeven be832f781d auxdisplay: ht16k33: Fix frame buffer device blanking ... [ Upstream commit 840fe258332544aa7321921e1723d37b772af7a9 ] As the ht16k33 frame buffer sub-driver does not register an fb_ops.fb_blank() handler, blanking does not work: $ echo 1 > /sys/class/graphics/fb0/blank sh: write error: Invalid argument Fix this by providing a handler that always returns zero, to make sure blank events will be sent to the actual device handling the backlight.
