Subject: [PATCH V4 1/6] iommu/arm-smmu: Fix the error path in arm_smmu_add_device
Date: Thu,  6 Jul 2017 15:07:00 +0530	[thread overview]
Message-ID: <1499333825-7658-2-git-send-email-vivek.gautam@codeaurora.org> (raw)
In-Reply-To: <1499333825-7658-1-git-send-email-vivek.gautam@codeaurora.org>

fwspec->iommu_priv is available only after arm_smmu_master_cfg
instance has been allocated. We shouldn't free it before that.
Also it's logical to free the master cfg itself without
checking for fwspec.
