[PATCH -next] i2c: efm32: Use devm_platform_get_and_ioremap_resource()

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

 



Make use of devm_platform_get_and_ioremap_resource() provided by
driver core platform instead of duplicated analogue. dev_err() is
removed because it has been done in devm_ioremap_resource().
