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

Hi Greg,

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

In file included from drivers/usb/host/ehci-hcd.c:113:
drivers/usb/host/ehci-dbg.c: In function 'debug_lpm_write':
drivers/usb/host/ehci-dbg.c:992: error: implicit declaration of function 'copy_from_user'

Caused by commit a3c0b4b257eeaefe4e6c8fbf5ddfe674242f1b9e ("USB: EHCI:
EHCI 1.1 addendum: preparation").  Presumably a missing include of
linux/uaccess.h ...

I applied this patch for today:

From: Stephen Rothwell <sfr@...b.auug.org.au>

Subject: [PATCH] usb: using copy_from_user in ehci-hcd requies the include of uaccess.h
