warning: (CAN_SOFTING_CS) selects CAN_SOFTING which has unmet direct dependencies (NET && CAN && CAN_DEV && HAS_IOMEM)

with this partial config:

CONFIG_CAN=m
# CONFIG_CAN_RAW is not set
# CONFIG_CAN_BCM is not set
# CAN Device Drivers
# CONFIG_CAN_VCAN is not set
CONFIG_CAN_SLCAN=m
# CONFIG_CAN_DEV is not set
CONFIG_CAN_SOFTING=m
CONFIG_CAN_SOFTING_CS=m
# CONFIG_CAN_DEBUG_DEVICES is not set

I understand the output, but I don't understand the cause well enough.
CAN_SOFTING=m has a 'depends on CAN_DEV'
Is it then possible to have CAN_SOFTING=m _and not_ CAN_DEV ?
