Subject: xhci-pci: set the dma max_seg_size
From: Ricardo Ribalda <ribalda@xxxxxxxxxxxx>
commit 93915a4170e9defd56a767a18e6c4076f3d18609 upstream.
Allow devices to have dma operations beyond 64K, and avoid warnings such
as:
xhci_hcd 0000:00:14.0: mapping sg segment longer than device claims to support [len=98304] [max=65536]
