[PATCH v1 3/6] platform/x86: intel_cht_int33fe: Convert software node array to group

Andy Shevchenko
2020-04-08T16:09:30Z

Code looks and be read cleaner when software nodes are defined individually.
Convert software node array to a group in order to achieve above.

While here, switch struct initializers to C99 standard.
