Since commit 84af7a6194 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the
following commend:
$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

tristate "Virtual Local CAN Interface (vcan)"
|
|
help
|
|
Similar to the network loopback devices, vcan offers a
|
|
virtual local CAN interface.
|
|
|
|
This driver can also be built as a module. If so, the module
|
|
will be called vcan.
|

tristate "Virtual CAN Tunnel (vxcan)"
|
|
help
|
|
Similar to the virtual ethernet driver veth, vxcan implements a
|
|
local CAN traffic tunnel between two virtual CAN network devices.
|
|
When creating a vxcan, two vxcan devices are created as pair.
|
|
When one end receives the packet it appears on its pair and vice
|
|
versa. The vxcan can be used for cross namespace communication.
|
|
|
|
In opposite to vcan loopback devices the vxcan only forwards CAN
|
|
frames to its pair and does *not* provide a local echo of sent
|
|
CAN frames. To disable a potential echo in af_can.c the vxcan driver
|
|
announces IFF_ECHO in the interface flags. To have a clean start
|
|
in each namespace the CAN GW hop counter is set to zero.
|
|
|
|
This driver can also be built as a module. If so, the module
|
|
will be called vxcan.

help
|
|
CAN driver for several 'low cost' CAN interfaces that are attached
|
|
via serial lines or via USB-to-serial adapters using the LAWICEL
|
|
ASCII protocol. The driver implements the tty linediscipline N_SLCAN.
|
|
|
|
As only the sending and receiving of CAN frames is implemented, this
|
|
driver should work with the (serial/USB) CAN hardware from:
|
|
www.canusb.com / www.can232.com / www.mictronics.de / www.canhack.de
|
|
|
|
Userspace tools to attach the SLCAN line discipline (slcan_attach,
|
|
slcand) can be found in the can-utils at the SocketCAN SVN, see
|
|
http://developer.berlios.de/projects/socketcan for details.
|
|
|
|
The slcan driver supports up to 10 CAN netdevices by default which
|
|
can be changed by the 'maxdev=xx' module option. This driver can
|
|
also be built as a module. If so, the module will be called slcan.

help
|

If enabled, CAN bit-timing parameters will be calculated for the
|
|
bit-rate specified via Netlink argument "bitrate" when the device
|
|
get started. This works fine for the most common CAN controllers
|
|
with standard bit-rates but may fail for exotic bit-rates or CAN
|
|
source clock frequencies. Disabling saves some space, but then the
|
|
bit-timing parameters must be specified directly using the Netlink
|
|
arguments "tq", "prop_seg", "phase_seg1", "phase_seg2" and "sjw".
|

If unsure, say Y.
