Subject: [PATCH] PCI: free of node in pci_scan_device's error path
Date: Sat, 23 Jan 2021 03:58:38 +0300 [thread overview]
Message-ID: <20210123005838.3623618-1-dmitry.baryshkov@linaro.org> (raw)
In the pci_scan_device() if pci_setup_device() fails for any reason, the
code will not release device's of_node by calling pci_release_of_node().
Fix that by calling the release function.
Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>
Fixes: 98d9f30c820d ("pci/of: Match PCI devices to OF nodes dynamically")
