The original patch uses a feature in lib/vsprintf.c to handle the invalid address when tring to print *_fw_module->man4_module_entry.name when the *rc_fw_module is NULL. This case is handled by check_pointer_msg() internally and turns the invalid pointer to '(efault)' for printing but it is hiding useful information about the circumstances. Change the print to emmit the name of the widget and a note on which side's fw_module is missing.
