Subject: [PATCH 3.2 015/199] usb: xhci-mem: use passed in GFP flags
 instead of GFP_KERNEL

3.2.87-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpenter@...cle.com>

commit c95a9f83711bf53faeb4ed9bbb63a3f065613dfb upstream.

We normally use the passed in gfp flags for allocations, it's just these
two which were missed.

Fixes: 22d45f01a836 ("usb/xhci: replace pci_*_consistent() with dma_*_coherent()")
