[PATCH 22/26] dm: core: Access device ofnode through functions

Simon Glass
2020-12-19T17:40:14Z

At present ofnode is present in the device even if it is never used. With
of-platdata this field is not used, so can be removed. In preparation for
this, change the access to go through inline functions.
