[PATCH 6.1 173/183] platform/x86/amd: Fix refcount leak in amd_pmc_probe

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Miaoqian Lin <linmq006@xxxxxxxxx>

[ Upstream commit ccb32e2be14271a60e9ba89c6d5660cc9998773c ]

pci_get_domain_bus_and_slot() takes reference, the caller should release
the reference by calling pci_dev_put() after use. Call pci_dev_put() in
the error path to fix this.
