linux-next: build failure after merge of the final tree (pm treerelated)

[Stephen Rothwell]

Hi ,

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

drivers/base/bus.o: In function `dev_pm_qos_add_ancestor_request':
bus.c:(.text+0x4c0): multiple definition of `dev_pm_qos_add_ancestor_request'
drivers/base/core.o:core.c:(.text+0x8ec): first defined here
drivers/base/dd.o: In function `dev_pm_qos_add_ancestor_request':
dd.c:(.text+0x418): multiple definition of `dev_pm_qos_add_ancestor_request'
drivers/base/core.o:core.c:(.text+0x8ec): first defined here
kernel/sysctl_binary.o: In function `dev_pm_qos_add_ancestor_request':
sysctl_binary.c:(.text+0x124): multiple definition of `dev_pm_qos_add_ancestor_request'

Caused by commit 513dcbda6199 ("PM / QoS: Introduce
dev_pm_qos_add_ancestor_request()") from the pm tree.

Please build with and without config options that protect new code ... :-(

I applied this patch for today:

Subject: [PATCH] PM / QoS: fix build problem with new
 dev_pm_qos_add_ancestor_request api
