The wakeup_cpu variable in omap4_enter_lowpower() is set but then is not used after this. Remove it to fix the compiler warning: arch/arm/mach-omap2/omap-mpuss-lowpower.c: In function âomap4_enter_lowpowerâ: arch/arm/mach-omap2/omap-mpuss-lowpower.c:230:15: warning: variable âwakeup_cpuâ set but not used [-Wunused-but-set-variable] Signed-off-by: Ben Dooks (Codethink) <ben.dooks@codethink.co.uk> --- Cc: Tony Lindgren <tony@atomide.com> Cc: Russell King <linux@armlinux.org.uk> Cc: linux-omap@vger.kernel.org Cc: linux-arm-kernel@lists.infradead.org --- arch/arm/mach-omap2/omap-mpuss-lowpower.c | 2 -- 1 file changed, 2 deletions(-)
