[PATCH -next/mmotm] net/can: fix softing build errors

[Randy Dunlap]

From: Randy Dunlap <randy.dunlap@xxxxxxxxxx>

Fix can/softing build errors due to kconfig error.

kconfig tells us about a problem...

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

and then this is what happens due to that kconfig problem:

ERROR: "register_candev" [drivers/net/can/softing/softing.ko] undefined!
ERROR: "alloc_candev" [drivers/net/can/softing/softing.ko] undefined!
ERROR: "can_bus_off" [drivers/net/can/softing/softing.ko] undefined!
ERROR: "close_candev" [drivers/net/can/softing/softing.ko] undefined!
ERROR: "free_candev" [drivers/net/can/softing/softing.ko] undefined!
ERROR: "unregister_candev" [drivers/net/can/softing/softing.ko] undefined!
ERROR: "alloc_can_skb" [drivers/net/can/softing/softing.ko] undefined!
ERROR: "open_candev" [drivers/net/can/softing/softing.ko] undefined!

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
