The newly added debug mode for the synaptics-rmi4 driver relies on the v4l2 interface and vb2_vmalloc, but those might be configured as loadable modules when the driver itself is built-in, resulting in a link failure: drivers/input/rmi4/rmi_core.o: In function `rmi_f54_remove': rmi_f54.c:(.text.rmi_f54_remove+0x14): undefined reference to `video_unregister_device' rmi_f54.c:(.text.rmi_f54_remove+0x20): undefined reference to `v4l2_device_unregister' drivers/input/rmi4/rmi_core.o: In function `rmi_f54_vidioc_s_input': rmi_f54.c:(.text.rmi_f54_vidioc_s_input+0x10): undefined reference to `video_devdata' drivers/input/rmi4/rmi_core.o: In function `rmi_f54_vidioc_g_input': rmi_f54.c:(.text.rmi_f54_vidioc_g_input+0x10): undefined reference to `video_devdata' drivers/input/rmi4/rmi_core.o: In function `rmi_f54_vidioc_fmt': rmi_f54.c:(.text.rmi_f54_vidioc_fmt+0x10): undefined reference to `video_devdata' drivers/input/rmi4/rmi_core.o: In function `rmi_f54_vidioc_enum_input': rmi_f54.c:(.text.rmi_f54_vidioc_enum_input+0x10): undefined reference to `video_devdata' drivers/input/rmi4/rmi_core.o: In function `rmi_f54_vidioc_querycap': ... The best workaround I could come up with is to disallow the debug mode unless it's actually possible to call it.
