Subject: [PATCH 4.14 102/164] iommu/vt-d: Fix a potential memory leak
4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Lu Baolu <baolu.lu@...ux.intel.com>
commit bbe4b3af9d9e3172fb9aa1f8dcdfaedcb381fc64 upstream.
A memory block was allocated in intel_svm_bind_mm() but never freed
in a failure path. This patch fixes this by free it to avoid memory
leakage.
