ARM: at91: unused variable in at91_pm_verify_clocks
The code using the variable 'i' in this function is conditional which results in a harmless compiler warning. Using the IS_ENABLED macro instead of #ifdef makes the code look nicer and gets rid of the warning. Without this patch, building at91sam9263_defconfig results in: /home/arnd/linux-arm/arch/arm/mach-at91/pm.c: In function 'at91_pm_verify_clocks': /home/arnd/linux-arm/arch/arm/mach-at91/pm.c:137:6: warning: unused variable 'i' [-Wunused-variable] Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Cc: Nicolas Ferre <nicolas.ferre@atmel.com>
