get compile-test failed report from lkp@xxxxxxxxx after the driver submitted. "ld.lld: error: undefined symbol: v4l2_fh_init" so, make CONFIG_STM32_DMA2D depends on CONFIG_VIDEO_DEV and CONFIG_VIDEO_V4L2 to fix this compile error. Fixes: bdbbd511ef0c ("media: stm32-dma2d: STM32 DMA2D driver") Reported-by: kernel test robot <lkp@xxxxxxxxx> Signed-off-by: Dillon Min <dillon.minfei@xxxxxxxxx> --- Hi Hans I found the dma2d driver was merged to linux-next. so submit this patch based on linux-next/master, to fix the compile test error. hope it's not too late for 5.16.
