Of the two paths leading to the "error" label in xen_swiotlb_init() one didn't allocate anything, while the other did already free what was allocated. Fixes: b82776005369 ("xen/swiotlb: Use the swiotlb_late_init_with_tbl to init Xen-SWIOTLB late when PV PCI is used") Signed-off-by: Jan Beulich <jbeulich@suse.com> Cc: stable@vger.kernel.org Reviewed-by: Christoph Hellwig <hch@lst.de> Link: https://lore.kernel.org/r/ce9c2adb-8a52-6293-982a-0d6ece943ac6@suse.com Signed-off-by: Juergen Gross <jgross@suse.com>
