[PATCH] misc: atmel_pwm: only build for supported platforms

[Nicolas Ferre]

On 08/05/2014 16:56, Arnd Bergmann :
> There is architecture code in mach-at91 that depends on the
> CONFIG_ATMEL_PWM symbol in order to call the soc-specific
> at91_add_device_pwm function. While all of this is about code
> that will be removed in the future, using DT probing and
> the PWM framework, we currently get a build failure:
> 
> 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.
