From: Jiri Pirko Date: Fri, 21 Oct 2016 14:07:23 +0000 (+0200) Subject: mlxsw: Convert resources into array X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c1a3831121f60f614fe92314d8c271d4d89d0a9a;p=linux-beck.git mlxsw: Convert resources into array Since the number of resources is going to get much bigger, ease up the addition by simly defining IDs. Convert the existing structure members to a set array, one for validity, one for values. Introduce a set of getters and setters for easy access.
