Subject: linux-next: build failure after merge of the final tree (staging
 tree related)

Hi all,

After merging the final tree, today's linux-next build (powerpc
allyesconfig) failed like this:

drivers/staging/dwc2/hcd.c: In function '_dwc2_hcd_urb_enqueue':
drivers/staging/dwc2/hcd.c:2387:3: error: implicit declaration of function 'bus_to_virt' [-Werror=implicit-function-declaration]
drivers/staging/dwc2/hcd.c:2387:7: warning: assignment makes pointer from integer without a cast [enabled by default]

Caused by commit 7359d482eb4d ("staging: HCD files for the DWC2 driver").

From Documentation/bus-virt-phys-mapping.txt:

"[ NOTE: The virt_to_bus() and bus_to_virt() functions have been
        superseded by the functionality provided by the PCI DMA interface
        (see Documentation/DMA-API-HOWTO.txt).  They continue
        to be documented below for historical purposes, but new code
        must not use them. --davidm 00/12/12 ]"

See also Documentation/DMA-API-HOWTO.txt.

I have added this patch for today:
