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/comedi/drivers/ni_labpc.c: In function 'labpc_ai_cmd':
drivers/staging/comedi/drivers/ni_labpc.c:980:9: error: implicit declaration of function 'virt_to_bus' [-Werror=implicit-function-declaration]

Probably caused by commit fa3cb2191091 ("staging: comedi: ni_labpc: split
out PCI support").

I have disabled this driver for today:

Ugh.. powerpc probably has CONFIG_ISA_DMA_API but not
CONFIG_VIRT_TO_BUS.

I'm looking for a fix now.

Stephen,

I just posted a patch that hopefully will fix this.

Please let me know if it works.

Hartley
