From b45c03f585ea9bb1af76c73e82195418c294919d Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Mon, 7 Sep 2015 10:39:27 +0100 Subject: arm: Use g_new() & friends where that makes obvious sense g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer, for two reasons. One, it catches multiplication overflowing size_t. Two, it returns T * rather than void *, which lets the compiler catch more type errors. This commit only touches allocations with size arguments of the form sizeof(T).
