[PATCH 21/26] dm: core: Use dev_has_ofnode() instead of dev_of_valid()

Simon Glass
2020-12-19T17:40:13Z

We have two functions which do the same thing. Standardise on
dev_has_ofnode() since there is no such thing as an 'invalid' ofnode in
normal operation: it is either null or missing.

Also move the functions into one place.
