Subject: PCI: hv: Add missing kfree(hbus) in hv_pci_probe()'s error handling path
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=42c3d41832ef4fcf60aaa6f748de01ad99572adf;p=linux.git

PCI: hv: Add missing kfree(hbus) in hv_pci_probe()'s error handling path

Now that we use kzalloc() to allocate the hbus buffer, we must call
kfree() in the error path as well to prevent memory leakage.

Fixes: 877b911a5ba0 ("PCI: hv: Avoid a kmemleak false positive caused by the hbus buffer")
