[RFC PATCH v1 05/12] renesas: Replace strstarts() by str_has_prefix().

From: laniel_francis
Date: Fri Dec 04 2020 - 12:05:26 EST


From: Francis Laniel <laniel_francis@xxxxxxxxxxxxxxxxxxx>

The two functions indicates if a string begins with a given prefix.
The only difference is that strstarts() returns a bool while str_has_prefix()
returns the length of the prefix if the string begins with it or 0 otherwise.
