From a8a31afad5ffa1c7de0cef1c4bc383b50f426bf8 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 20 Nov 2015 22:47:41 +0100 Subject: [PATCH] fbdev: auo_k190x: avoid unused function warnings The auo_k190x framebuffer driver encloses the power-management functions in #ifdef CONFIG_PM, but the auok190x_suspend/resume functions are only really used when CONFIG_PM_SLEEP is also set, as a frequent gcc warning shows: drivers/video/fbdev/auo_k190x.c:859:12: warning: 'auok190x_suspend' defined but not used drivers/video/fbdev/auo_k190x.c:899:12: warning: 'auok190x_resume' defined but not used This changes the driver to remove the #ifdef and instead mark the functions as __maybe_unused, which is a nicer anyway, as it provides build testing for all the code in all configurations and is harder to get wrong.
