Add a resource managed devm_iio_device_alloc()/devm_iio_device_free()
to automatically clean up any allocations made by IIO drivers,
thus leading to simplified IIO drivers code.

In addition, this will allow IIO drivers to use other devm_*() API
(like devm_request_irq) and don't care about the race between
iio_device_free() and the release of resources by Device core
during driver removing.

There are no users of this macro left and we have come to the conclusion that it
is not a good idea to expose the raw chip reset to userspace so the macro is
very unlikely to be used in new drivers.

There is no reason why userspace should want to trigger a manual reset of the

Keeping Makefile and Kconfig entries in alphabetical order usually works better
than just appending new entries at the end, since it reduces the amount of
conflicts. This patch adds a comment to the IIO Kconfig and Makefile files to
document that the entries should be kept in alphabetical order.

Also reorder those  entries which weren't in alphabetical order yet.

Add a MODULE_DEVICE_TABLE in order to let hotplug mechanisms automatically
load the driver.

This makes it also possible to use the usual driver name instead of
HID-SENSOR-2000xx which isn't very descriptive in kernel messages.

Turns out that the ll_crypto_alloc_blkcipher() wrapper didn't even do
anything, and is probably wrong, so it's not needed, just call the

Almost all of these are just a straight function name rename, so fix
them all up to call the crypto layer properly, no need for a #define to
hide things.
