Subject[PATCH] auxdisplay: ht16k33: select CONFIG_FB_SYS_FOPS
Date
The new driver caused a rare randconfig failure:

drivers/auxdisplay/ht16k33.o:(.data.ht16k33_fb_ops+0xc): undefined reference to `fb_sys_read'
drivers/auxdisplay/ht16k33.o:(.data.ht16k33_fb_ops+0x10): undefined reference to `fb_sys_write'

This selects the respective helper module, like all other
such drivers do.

Fixes: 8992da44c680 ("auxdisplay: ht16k33: Driver for LED controller")
