Subject: linux-next: build failures after merge of the final tree (usb tree
 related)

Hi ,

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

In file included from drivers/usb/host/ehci-platform.c:28:0:
drivers/usb/host/ehci.h: In function 'ehci_readl':
drivers/usb/host/ehci.h:662:3: error: implicit declaration of function 'readl_be' [-Werror=implicit-function-declaration]
drivers/usb/host/ehci.h:663:3: error: implicit declaration of function 'readl' [-Werror=implicit-function-declaration]

drivers/usb/host/ehci.h:675:3: error: implicit declaration of function 'writel' [-Werror=implicit-function-declaration]

Caused by commit 99f91934a907 ("USB: EHCI: make ehci-platform a separate
driver") from the usb tree.

I have reverted that commit for today.

I then got:

Which is caused by commit 3e0232039967 ("USB: EHCI: prepare to make
ehci-hcd a library module").

I have added the following patch to disable the chipidea driver for now:
