Subject: [PATCH AUTOSEL 6.1 02/60] iommu/amd: Fix error handling for pdev_pri_ats_enable()
Date: Fri,  3 Mar 2023 16:42:16 -0500	[thread overview]
Message-ID: <20230303214315.1447666-2-sashal@kernel.org> (raw)
In-Reply-To: <20230303214315.1447666-1-sashal@kernel.org>

From: Vasant Hegde <vasant.hegde@amd.com>

[ Upstream commit 080920e52148b4fbbf9360d5345fdcd7846e4841 ]

Current code throws kernel warning if it fails to enable pasid/pri [1].
Do not call pci_disable_[pasid/pri] if pci_enable_[pasid/pri] failed.
