Input: bcm5974 - set missing URB_NO_TRANSFER_DMA_MAP urb flag
commit c42e65664390be7c1ef3838cd84956d3a2739d60 upstream.
The bcm5974 driver does the allocation and dma mapping of the usb urb
data buffer, but driver does not set the URB_NO_TRANSFER_DMA_MAP flag
to let usb core know the buffer is already mapped.
usb core tries to map the already mapped buffer, causing a warning:
"xhci_hcd 0000:00:14.0: rejecting DMA map of vmalloc memory"
Fix this by setting the URB_NO_TRANSFER_DMA_MAP, letting usb core
know buffer is already mapped by bcm5974 driver
