Subject: [PATCH] s390/sclp_vt220: fix unused function warning
Date:   Mon, 27 Sep 2021 14:56:47 -0700

When CONFIG_SCLP_VT220_TTY=y and CONFIG_SCLP_VT220_CONSOLE is not set:

../drivers/s390/char/sclp_vt220.c:771:13: warning: '__sclp_vt220_flush_buffer' defined but not used [-Wunused-function]
  771 | static void __sclp_vt220_flush_buffer(void)

so move this function inside the #ifdef block where it is used.

Sorry, I can't determine what the Fixes: tag for this should be
(missing some git fu).
