Oops, a script started sending "queued" messages for everything that
had "y" in the subject. Sorry about that.

With the recent switch from fbdev-generic to fbdev-dma, the driver now requires the DRM GEM DMA helpers. This dependency is missing, and will cause a link failure if fbdev emulation is enabled. Add the missing dependency. Fixes: 0992284b4fe4 ("drm/mediatek: Use fbdev-dma") Signed-off-by: Chen-Yu Tsai <wenst@chromium.org> --- The commit this patch fixes is in drm-misc-next. Ideally this patch should be applied on top of it directly. CK, could you give your ack for it? drivers/gpu/drm/mediatek/Kconfig | 1 + 1 file changed, 1 insertion(+)
