#1358429 — linux-next: build failure after merge of the kbuild tree

Message-ID<rd72z-M3-41@gated-at.bofh.it>
Hi Michal,

After merging the kbuild tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/gpu/drm/gma500/mdfld_dsi_output.c:407:39: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types]
  .dpms = /*drm_helper_connector_dpms*/mdfld_dsi_connector_dpms,
                                       ^

Caused by commit

  ea8daa7b9784 ("kbuild: Add option to turn incompatible pointer check into error")

Maybe this needs to be optional?

I have reverted that commit for today.

Cheers,
Stephen Rothwell

A fix should be on the way via drm-misc:

https://lkml.org/lkml/2016/2/25/397

Though I don't know what the exact status is (and I haven't really
understood the flow of the patches as far)

cheers,
daniel

Right. Stephen, could you perhaps move the kbuild tree down in your list
a bit, so that the fixes are present?

Thanks,
Michal

Done.

Now you just need to make sure Linus gets them in the right order :-)
