From d701ec326a31945d1533b438a6feab753829b738 Mon Sep 17 00:00:00 2001 From: Shannon Nelson Date: Thu, 22 Oct 2020 16:55:29 -0700 Subject: [PATCH] ionic: clean up sparse complaints The sparse complaints around the static_asserts were obscuring more useful complaints. So, don't check the static_asserts, and fix the remaining sparse complaints.
