# grep CONFIG_SYSFS .config CONFIG_SYSFS_DEPRECATED=y CONFIG_SYSFS_DEPRECATED_V2=y CONFIG_SYSFS=y
and re-bisected. Now it turned out that
39aba963 "driver core: remove CONFIG_SYSFS_DEPRECATED_V2 but keep it for block devices"
is the commit which caused these error messages.
Guessing from error messages, changes in drivers/scsi/hosts.c and drivers/scsi/scsi_scan.c might be involved.
