xhci-pci: set the dma max_seg_size
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] Cc: stable@vger.kernel.org Cc: Takashi Iwai <tiwai@suse.de> Signed-off-by: Ricardo Ribalda <ribalda@chromium.org> Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Link: https://lore.kernel.org/r/20230116142216.1141605-2-mathias.nyman@linux.intel.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
