Subject: [PATCH] nvme-pci: fixing memory leak in probe teardown path
References: bsc#1012628
Patch-mainline: 6.2.10
Git-commit: a61d265533b7fe0026a02a49916aa564ffe38e4c
[ Upstream commit a61d265533b7fe0026a02a49916aa564ffe38e4c ]
In case the nvme_probe teardown path is triggered the ctrl ref count does
not reach 0 thus creating a memory leak upon failure of nvme_probe.
