CVE-2022-50520

Medium 5.5

In the Linux kernel, the following vulnerability has been resolved: drm/radeon: Fix PCI device refcount leak in radeon_atrm_get_bios() As comment of pci_get_class() says, it returns a pci_device with its refcount increased and decreased the refcount for the input parameter @from if it is not NULL. If we break the loop in radeon_atrm_get_bios() with 'pdev' not NULL, we need to call pci_dev_put() to decrease the refcount. Add the missing pci_dev_put() to avoid refcount leak.
