useful after a break or return.

if(e2) { ... return ...; }
-else
         s1

staging: iio: adc: Replace of_iomap() with devm_ioremap_resource()

2016-03-12T06:09:09+00:00

The adc driver uses of_iomap() which doesn't request the resource and
isn't device managed so error handling is needed. of_iomap() is mainly
used in cases where there is no driver or struct device so a switch to
devm_ functions is required.

This patch switches to use devm_ioremap_resource() instead which
automatically requests the resource and is freed when the driver
detaches.

Removed the error handling to unmap I/O registers i.e.
iounmap() in probe and remove functions of this driver and
consequently removed an unnecessary label.

staging: iio: ade7854: use devm_iio_device_register

2016-03-12T06:09:09+00:00

Replace iio_device_register with the device managed version.
This change is safe because it does not change the order of
any device removal actions. Unregistering the device was the
only removal action. The newly emptied .remove functions are
deleted.
