I did not add a version or changelog because I believe this is
essentially a different patch, with different justification and
different API that is being used.
The first one was a simple switch to devm_fwnode_gpiod_get(), the new
one is abandoning the use of explicit node reference, and instead uses
standard devm_gpiod_get() to get a GPIO assigned to a device +
gpiod_set_consumer_name() to maintain the naming.
