Subject: [RFC PATCH v2 8/9] fpga: dfl: migrate dfl_get_feature_by_id() to dfl_feature_dev_data
This change separates out most of the symbol name changes required by this
patch series for the function: dfl_get_feature_by_id(). This is done to
split a single monolithic change into multiple, smaller patches at the
request of the maintainer.
Signed-off-by: Peter Colberg <peter.colberg@...el.com>

v2:
- Split monolithic patch into series at request of maintainer
