From 37cce26b32142f09a8967f6d238178af654b20de Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Wed, 21 Sep 2011 22:47:55 +0200 Subject: PM / VT: Cleanup #if defined uglyness and fix compile error Introduce the config option CONFIG_VT_CONSOLE_SLEEP in order to cleanup the #if defined ugliness for the vt suspend support functions. Note that CONFIG_VT_CONSOLE is already dependant on CONFIG_VT. The function pm_set_vt_switch is actually dependant on CONFIG_VT and not CONFIG_PM_SLEEP. This fixes a compile error when CONFIG_PM_SLEEP is not set: drivers/tty/vt/vt_ioctl.c:1794: error: redefinition of 'pm_set_vt_switch' include/linux/suspend.h:17: error: previous definition of 'pm_set_vt_switch' was here Also, remove the incorrect path from the comment in console.c. [rjw: Replaced #if defined() with #ifdef in suspend.h.] Signed-off-by: H Hartley Sweeten Acked-by: Arnd Bergmann Signed-off-by: Rafael J.
