From b3c3890489f6d3794916958d1663ab6aecb0290b Mon Sep 17 00:00:00 2001 From: Bruce Allan Date: Mon, 29 Jun 2020 17:27:45 -0700 Subject: [PATCH] ice: avoid unnecessary single-member variable-length structs There are a number of structures that consist of a one-element array as the only struct member. Some of those are unused so remove them. Others are used to index into a buffer/array consisting of a variable number of a different data or structure type. Those are unnecessary since we can use simple pointer arithmetic or index directly into the buffer to access individual elements of the buffer/array. Additional code cleanups were done near areas affected by this change.
