From b4a512b8bf7185787e291cddad3b6457b2367120 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 13 Jan 2016 21:59:23 +0100 Subject: serial/omap: mark wait_for_xmitr as __maybe_unused The wait_for_xmitr() function is only used if CONFIG_CONSOLE_POLL or CONFIG_SERIAL_OMAP_CONSOLE are set, but when both are disabled, the compiler warns about it being unused: drivers/tty/serial/omap-serial.c:1168:13: warning: 'wait_for_xmitr' defined but not used [-Wunused-func We could add more #ifdefs to work around it, but adding __maybe_unused seems nicer.
