I tried turning the 'select I2C' from FB_DDC into a "depends on I2C",
which seems like the more appropriate type of dependency, but that
causes a slew of new warnings because now all of a sudden some symbols
have unmet direct dependencies.

This is really quite messy. The only solution I can think of would be to
provide stubs for all of the GPIO API so that the dependency can be
dropped again. That's a little extreme and shouldn't be necessary, but I
don't see any other way to untangle this mess, I'm afraid.

Arnd, any ideas?

Thierry

linux-next: build warning after merge of the drm-panel tree

2015-03-24 Thread Stephen Rothwell 
Hi Thierry,

After merging the drm-panel tree, today's linux-next build (powerpc
ppc64_defconfig) produced this warning:

drivers/video/fbdev/Kconfig:5:error: recursive dependency detected!
drivers/video/fbdev/Kconfig:5:  symbol FB is selected by DRM_KMS_FB_HELPER
drivers/gpu/drm/Kconfig:34: symbol DRM_KMS_FB_HELPER depends on 
DRM_KMS_HELPER
drivers/gpu/drm/Kconfig:28: symbol DRM_KMS_HELPER is selected by DRM_PTN3460
drivers/gpu/drm/bridge/Kconfig:6:   symbol DRM_PTN3460 depends on GPIOLIB

Introduced by commit 6a43766f6ef3 ("drm/bridge: ps8622 and ptn3460
depend on gpiolib").
