Subject[PATCH AUTOSEL 5.2 12/59] irqchip/gic-v3-its: Free unused vpt_page when alloc vpe table fail
Date
From: Nianyao Tang <tangnianyao@huawei.com>

[ Upstream commit 34f8eb92ca053cbba2887bb7e4dbf2b2cd6eb733 ]

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.
