Hi all, After merging the scsi-mkp tree, today's linux-next build (x86_64 allmodconfig) failed like this: ERROR: modpost: "exynos_ufs_dump_info" [drivers/scsi/ufs/ufs-exynos.ko] undefined! ERROR: modpost: "exynos_ufs_init_dbg" [drivers/scsi/ufs/ufs-exynos.ko] undefined! ERROR: modpost: "exynos_ufs_cmd_log_start" [drivers/scsi/ufs/ufs-exynos.ko] undefined! Caused by commits c3b5e96ef515 ("scsi: ufs: exynos: Introduce command history") 957ee40d413b ("scsi: ufs: exynos: Implement dbg_register_dump") I applied the following patch for now.
