xhci: dbc: don't use generic xhci ring allocation functions for dbc.
The generic xhci ring allocations code needs struct xhci_hcd pointer, and it allocates memory for the rings from dma pools created for the xhci device. In order to decouple xhci and DbC we have to create our own ring allocation and free routines for DbC Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Link: https://lore.kernel.org/r/20200723144530.9992-20-mathias.nyman@linux.intel.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
