Hi Tobias,
Lately I've submitted patches to Gregs (char-misc) git repo and they got bounced because the kbuild bot threw a warning:
warning: (PMAC_BACKLIGHT && DRM_NOUVEAU && HT16K33 && FB_TFT) selects FB_BACKLIGHT which has unmet direct dependencies (HAS_IOMEM && FB)
My patched added a new driver named HT16K33, but..
I believe the warning is the result of a dependency issue made possible by this commit: https://kernel.googlesource.com/pub/scm/linux/kernel/git/gregkh/char-misc/+/fc497ed8361f34e465f31e9babcb88efe38fe433
The kbuild bots configuration file stated: CONFIG_HAS_IOMEM=y CONFIG_DRM_NOUVEAU=y CONFIG_DRM_NOUVEAU_BACKLIGHT=y CONFIG_FB_BACKLIGHT=y # CONFIG_FB is not set
PMAC_BACKLIGHT, HT16K33 and FB_TFT ware not mentioned in the config file. I've attached the config file to this email.
FB_BACKLIGHT depends on FB like so:
(drivers/video/fbdev/Kconfig) config FB_BACKLIGHT bool depends on FB ...
In your commit the 'select FB' is removed from the config DRM_NOUVEAU in the drivers/gpu/drm/nouveau/Kconfig file but DRM_NOUVEAU still selects FB_BACKLIGHT when using DRM_NOUVEAU_BACKLIGHT.
Is no one else selects FB, the warning mentioned above is raised.
Would you like to verify this?
Regards,
