Use devm_request_irq() to request the interrupt, so we can avoid having to manually clean this up. Use the dev_err_probe() helper to simplify error handling during probe. This also handle scenario, when EDEFER is returned and useless error is printed. Changes in v2: - Also use devm_request_irq() and dev_err_probe() to clean up the at91_adc. - Split the at91_adc patch out to be a new patch set.
