imx-mipi-csis uses interfaces that are made available by VIDEO_DEV, so the driver should depend on VIDEO_DEV to eliminate build errors. Fixes these build errors: aarch64-linux-ld: drivers/media/platform/nxp/imx-mipi-csis.o: in function `mipi_csis_calculate_params': imx-mipi-csis.c:(.text+0x2ec): undefined reference to `v4l2_get_link_freq' aarch64-linux-ld: drivers/media/platform/nxp/imx-mipi-csis.o: in function `mipi_csis_async_register': imx-mipi-csis.c:(.text+0x464): undefined reference to `v4l2_async_nf_init' aarch64-linux-ld: imx-mipi-csis.c:(.text+0x48c): undefined reference to `v4l2_fwnode_endpoint_parse' aarch64-linux-ld: imx-mipi-csis.c:(.text+0x538): undefined reference to `__v4l2_async_nf_add_fwnode_remote' aarch64-linux-ld: imx-mipi-csis.c:(.text+0x56c): undefined reference to `v4l2_async_subdev_nf_register' aarch64-linux-ld: imx-mipi-csis.c:(.text+0x57c): undefined reference to `v4l2_async_register_subdev' aarch64-linux-ld: drivers/media/platform/nxp/imx-mipi-csis.o: in function `mipi_csis_notify_bound': imx-mipi-csis.c:(.text+0x5e0): undefined reference to `v4l2_create_fwnode_links_to_pad' aarch64-linux-ld: drivers/media/platform/nxp/imx-mipi-csis.o: in function `mipi_csis_probe': imx-mipi-csis.c:(.text+0x1088): undefined reference to `v4l2_subdev_init' aarch64-linux-ld: imx-mipi-csis.c:(.text+0x1148): undefined reference to `v4l2_async_nf_unregister' aarch64-linux-ld: imx-mipi-csis.c:(.text+0x1150): undefined reference to `v4l2_async_nf_cleanup' aarch64-linux-ld: imx-mipi-csis.c:(.text+0x1158): undefined reference to `v4l2_async_unregister_subdev' aarch64-linux-ld: drivers/media/platform/nxp/imx-mipi-csis.o: in function `mipi_csis_set_fmt': imx-mipi-csis.c:(.text+0x1348): undefined reference to `v4l_bound_align_image' aarch64-linux-ld: drivers/media/platform/nxp/imx-mipi-csis.o: in function `mipi_csis_s_stream': imx-mipi-csis.c:(.text+0x14bc): undefined reference to `v4l2_subdev_call_wrappers' aarch64-linux-ld: imx-mipi-csis.c:(.text+0x14c0): undefined reference to `v4l2_subdev_call_wrappers' aarch64-linux-ld: imx-mipi-csis.c:(.text+0x1624): undefined reference to `v4l2_subdev_call_wrappers' aarch64-linux-ld: imx-mipi-csis.c:(.text+0x1628): undefined reference to `v4l2_subdev_call_wrappers' aarch64-linux-ld: imx-mipi-csis.c:(.text+0x16d0): undefined reference to `v4l2_subdev_call_wrappers' aarch64-linux-ld: drivers/media/platform/nxp/imx-mipi-csis.o:imx-mipi-csis.c:(.text+0x16d4): more undefined references to `v4l2_subdev_call_wrappers' follow aarch64-linux-ld: drivers/media/platform/nxp/imx-mipi-csis.o: in function `mipi_csis_remove': aarch64-linux-ld: drivers/media/platform/nxp/imx-mipi-csis.o:(.rodata+0x4b8): undefined reference to `v4l2_subdev_get_fwnode_pad_1_to_1' aarch64-linux-ld: drivers/media/platform/nxp/imx-mipi-csis.o:(.rodata+0x4c8): undefined reference to `v4l2_subdev_link_validate' Fixes: 46fb99951fe2 ("media: platform: place NXP drivers on a separate dir") Signed-off-by: Randy Dunlap <rdunlap@xxxxxxxxxxxxx> Reported-by: kernel test robot <lkp@xxxxxxxxx> Cc: Laurent Pinchart <laurent.pinchart@xxxxxxxxxxxxxxxx> Cc: Mauro Carvalho Chehab <mchehab@xxxxxxxxxx> Cc: Philipp Zabel <p.zabel@xxxxxxxxxxxxxx> Cc: linux-media@xxxxxxxxxxxxxxx --- drivers/media/platform/nxp/Kconfig | 1 + 1 file changed, 1 insertion(+) --- linux-next-20220331.orig/drivers/media/platform/nxp/Kconfig +++ linux-next-20220331/drivers/media/platform/nxp/Kconfig @@ -7,6 +7,7 @@ comment "NXP media platform drivers" config VIDEO_IMX_MIPI_CSIS tristate "NXP MIPI CSI-2 CSIS receiver found on i.MX7 and i.MX8 models" depends on ARCH_MXC || COMPILE_TEST + depends on VIDEO_DEV select MEDIA_CONTROLLER select V4L2_FWNODE select VIDEO_V4L2_SUBDEV_API
