Before addressing the FB_CORE issue, patch 1 first resolves a problem with BACKLIGHT_CLASS_DEVICE. A number of fbdev drivers select it, which results in a recursive-dependency error after patch has been applied. Making these drivers (or parts of them) depend on BACKLIGHT_CLASS_DEVICE fixes this. Patch 2 selects FB_CORE for DRM_GEM_DMA_HELPER and DRM_TTM_HELPER. This is necessary with the recently added DRM client library. Patch 3 is the second half of the patch provided by Arnd at [1]. It could not yet be merged because of the issues fixed by patch 1. Side note: For the majority of graphics drivers, backlight functionality depends on BACKLIGHT_CLASS_DEVICE. In a few cases drivers select the Kconfig token automatically. These drivers should be updated to depends on the token as well, such that backlight functionality is fully user- controlled. v2: - s/BACKLIGHT_DEVICE_CLASS/BACKLIGHT_CLASS_DEVICE (Helge) - Fix fbdev driver-dependency corner case (Arnd) [1] https://patchwork.freedesktop.org/series/141411/ Arnd Bergmann (1): drm: rework FB_CORE dependency Thomas Zimmermann (2): fbdev: Fix recursive dependencies wrt BACKLIGHT_CLASS_DEVICE drm/fbdev: Select FB_CORE dependency for fbdev on DMA and TTM drivers/auxdisplay/Kconfig | 2 +- drivers/gpu/drm/Kconfig | 3 +++ drivers/macintosh/Kconfig | 1 + drivers/staging/fbtft/Kconfig | 1 + drivers/video/fbdev/Kconfig | 18 +++++++++++++----- drivers/video/fbdev/core/Kconfig | 3 +-- 6 files changed, 20 insertions(+), 8 deletions(-)
