> There is architecture code in mach-at91 that depends on the

> at91_add_device_pwm function. While all of this is about code
> that will be removed in the future, using DT probing and

> arch/arm/mach-at91/built-in.o: In function `at91_pwm_leds':
> arch/arm/mach-at91/leds.c:88: undefined reference to `at91_add_device_pwm'

> This patch ensures we only try to build this driver on
> platforms on which it will build and work.
