The new PRE/PRG driver code causes a link failure when DRM is disabled:

Adding a Kconfig dependency on DRM means we don't run into this problem any more. This might not be the best solution though, as the ipu seems to have been intentionally kept separate from DRM in the past.

Originally sent on March 21, but got no reply for it. Resending unchanged as it is still needed in v4.13-rc1
thank you for fix and for the resend. I have the original patch in my inbox, I'm sorry I overlooked it.
I would still like to keep the ipu-v3 driver buildable without DRM enabled. For now, I have applied your patch as is.
