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superseded by the functionality provided by the PCI DMA interface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:
