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.
