net: hns3: fix oops when unload drivers paralleling
[ Upstream commit 92e5995773774a3e70257e9c95ea03518268bea5 ]
When unload hclge driver, it tries to disable sriov first for each
ae_dev node from hnae3_ae_dev_list. If user unloads hns3 driver at
the time, because it removes all the ae_dev nodes, and it may cause
oops.
But we can't simply use hnae3_common_lock for this. Because in the
process flow of pci_disable_sriov(), it will trigger the remove flow
of VF, which will also take hnae3_common_lock.
To fixes it, introduce a new mutex to protect the unload process.
Fixes: 0dd8a25f355b ("net: hns3: disable sriov before unload hclge layer")
