auxdisplay: panel: Fix missing print function pointer
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> Signed-off-by: Lars Poeschel <poeschel@lemonage.de> Signed-off-by: Miguel Ojeda <ojeda@kernel.org>
