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

Hi Dave,

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

drivers/gpu/drm/amd/powerplay/smumgr/ci_smc.o:(.opd+0xd8): multiple definition of `ci_send_msg_to_smc'
drivers/gpu/drm/radeon/ci_smc.o:(.opd+0xc0): first defined here
drivers/gpu/drm/amd/powerplay/smumgr/ci_smc.o: In function `.ci_send_msg_to_smc':
(.text+0xea0): multiple definition of `.ci_send_msg_to_smc'
drivers/gpu/drm/radeon/ci_smc.o:(.text+0x760): first defined here


Caused by commit

  9f4b35411cfe ("drm/amd/powerplay: add CI asics support to smumgr (v3)")

I applied the following patch for today:
