[PATCH 03/38] coccinelle: Add an iio_no_owner semantic patch to drop driver_owner

[Jonathan Cameron <jic23@kernel.org>]

After some macro magic has made the core code assign this appropriately
the field isn't used.  This patch automates the removal of the relevant
assignments.

Will be removed again once all instances have been dealt with and the field
is finally removed.
