[PATCH 5.13 557/800] i40e: Fix error handling in i40e_vsi_open

From: Greg Kroah-Hartman
Date: Mon Jul 12 2021 - 04:50:44 EST


From: Dinghao Liu <dinghao.liu@xxxxxxxxxx>

[ Upstream commit 9c04cfcd4aad232e36306cdc5c74cd9fc9148a7e ]

When vsi->type == I40E_VSI_FDIR, we have caught the return value of
i40e_vsi_request_irq() but without further handling. Check and execute
memory clean on failure just like the other i40e_vsi_request_irq().

Fixes: 8a9eb7d3cbcab ("i40e: rework fdir setup and teardown")
