[PATCH 1/2] iio: adc: mxs-lradc: Use devm_ioremap_resource()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



By using devm_ioremap_resource() the code can be simplified, as we
no longer need to check whether platform_get_resource() succeeded
or not, as this check is already performed in devm_ioremap_resource().
