The above mentioned file provides an OF API that's deprecated. There is no agnostic alternatives to it and we have to open code the logic which was hidden behind of_mm_gpiochip_add_data(). Note, most of the GPIO drivers are using their own labeling schemas and resource retrieval that only a few may gain of the code deduplication, so whenever alternative is appear we can move drivers again to use that one. As a side effect this change fixes a potential memory leak on an error path, if of_mm_gpiochip_add_data() fails.
