Also, riscv allmodconfig with the error:

drivers/media/platform/nxp/imx8-isi/imx8-isi-core.c:328:12: error:
'mxc_isi_pm_resume' defined but not used [-Werror=unused-function]
  328 | static int mxc_isi_pm_resume(struct device *dev)
      |            ^~~~~~~~~~~~~~~~~
drivers/media/platform/nxp/imx8-isi/imx8-isi-core.c:314:12: error:
