Subject[PATCH] auxdisplay: panel: Fix missing print function pointer
Date
From: Lars Poeschel <poeschel@lemonage.de>

charlcd drivers need to provide some print function to charlcd. For
hd44780 based panel driver this function was missing. We provide the
generic hd44780_common_print function which should be suitable.

Fixes: b26deabb1d915fe87d395081bbd3058b938dee89 ("auxdisplay: hd44780_common_print")
Reported-by: kernel test robot <oliver.sang@intel.com>
