From b4ea62123624ca194f9d217aecd9d91a4ae28e72 Mon Sep 17 00:00:00 2001 From: Zenghui Yu Date: Sun, 10 Feb 2019 05:24:10 +0000 Subject: [PATCH] irqchip/gic-v3-its: Avoid parsing _indirect_ twice for Device table commit 8d565748b6035eeda18895c213396a4c9fac6a4c upstream. In current logic, its_parse_indirect_baser() will be invoked twice when allocating Device tables. Add a *break* to omit the unnecessary and annoying (might be ...) invoking.
