Subject: linux-next: build failure after merge of the acpi tree

Hi Len,

After merging the acpi tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

In file included from drivers/video/output.c:25:
include/linux/video_output.h: In function 'video_output_register':
include/linux/video_output.h:49: error: implicit declaration of function 'ERR_PTR'
include/linux/video_output.h:49: warning: return makes pointer from integer without a cast
In file included from drivers/video/output.c:27:
include/linux/err.h: At top level:
include/linux/err.h:22: error: conflicting types for 'ERR_PTR'
include/linux/video_output.h:49: note: previous implicit declaration of 'ERR_PTR' was here
drivers/video/output.c:84: error: redefinition of 'video_output_register'
include/linux/video_output.h:44: note: previous definition of 'video_output_register' was here
drivers/video/output.c:114: error: redefinition of 'video_output_unregister'
include/linux/video_output.h:51: note: previous definition of 'video_output_unregister' was here

Caused by commit 16d21716c8849c3283d1b9e590e6fe8d1966f4b7 ("ACPI: video:
fix build for VIDEO_OUTPUT_CONTROL=n").  See Rule 1 in
Documentation/SubmitChecklist.

I have used the version of the acpi tree from next-20101201 for today.
