iio: at91_adc.c build error

hi Lars-Peter,

Seems there is no devm_kcalloc API available at this moment (in linux-next tree).

I got below build error:
drivers/iio/adc/at91_adc.c: In function 'at91_adc_channel_init':
drivers/iio/adc/at91_adc.c:126: error: implicit declaration of function 'devm_kcalloc' drivers/iio/adc/at91_adc.c:127: warning: assignment makes pointer from integer without a cast drivers/iio/adc/at91_adc.c: In function 'at91_adc_trigger_init':

Ok, now I feel stupid...

Do you want to sent a revert or should I do it?
