Subject: [PATCH v2] irqchip/gic-v3-its: Free unused vpt_page when alloc vpe table fail
Date: Fri, 26 Jul 2019 17:32:57 +0800	[thread overview]
Message-ID: <1564133577-57866-1-git-send-email-zhangshaokun@hisilicon.com> (raw)
In-Reply-To: <1564105905-15410-1-git-send-email-zhangshaokun@hisilicon.com>

From: Nianyao Tang <tangnianyao@huawei.com>

In its_vpe_init, when its_alloc_vpe_table fails, we should free
vpt_page allocated just before, instead of vpe->vpt_page.
Let's fix it.
