Subject: ARM: at91: fixed unresolved symbol "at91_pm_set_standby" when built without CONFIG_PM
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7093bf2b7195541281cb711e31c027a8d826c6df;p=linux-beck.git

ARM: at91: fixed unresolved symbol "at91_pm_set_standby" when built without CONFIG_PM

If CONFIG_PM is not defined, then arch/arm/mach-at91/pm.c is not
compiled in.  This patch creates an inline function that does nothing
if CONFIG_PM is not defined.
