Subject: [PATCH AUTOSEL 4.4 01/17] iommu/arm-smmu: Free context bitmap in the err path of arm_smmu_init_domain_context
Date: Sat, 26 Oct 2019 09:22:45 -0400 [thread overview]
Message-ID: <20191026132302.4622-1-sashal@kernel.org> (raw)
From: Liu Xiang <liuxiang_1999@126.com>
[ Upstream commit 6db7bfb431220d78e34d2d0afdb7c12683323588 ]
When alloc_io_pgtable_ops is failed, context bitmap which is just allocated
by __arm_smmu_alloc_bitmap should be freed to release the resource.
