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/'

help
|
|
Controller Area Network (CAN) is a slow (up to 1Mbit/s) serial
|
|
communications protocol. Development of the CAN bus started in
|
|
1983 at Robert Bosch GmbH, and the protocol was officially
|
|
released in 1986. The CAN bus was originally mainly for automotive,
|
|
but is now widely used in marine (NMEA2000), industrial, and medical
|
|
applications. More information on the CAN network protocol family
|
|
PF_CAN is contained in <Documentation/networking/can.rst>.
|
|
|
|
If you want CAN support you should say Y here and also to the
|
|
specific driver for your controller(s) below.

help
|
|
The raw CAN protocol option offers access to the CAN bus via
|
|
the BSD socket API. You probably want to use the raw socket in
|
|
most cases where no higher level protocol is being used. The raw
|
|
socket has several filter options e.g. ID masking / error frames.
|
|
To receive/send raw CAN messages, use AF_CAN with protocol CAN_RAW.

help
|
|
The Broadcast Manager offers content filtering, timeout monitoring,
|
|
sending of RTR frames, and cyclic CAN messages without permanent user
|
|
interaction. The BCM can be 'programmed' via the BSD socket API and
|
|
informs you on demand e.g. only on content updates / timeouts.
|
|
You probably want to use the bcm socket in most cases where cyclic
|
|
CAN messages are used on the bus (e.g. in automotive environments).
|
|
To use the Broadcast Manager, use AF_CAN with protocol CAN_BCM.

help
|
|
The CAN Gateway/Router is used to route (and modify) CAN frames.
|
|
It is based on the PF_CAN core infrastructure for msg filtering and
|
|
msg sending and can optionally modify routed CAN frames on the fly.
|
|
CAN frames can be routed between CAN network interfaces (one hop).
|
|
They can be modified with AND/OR/XOR/SET operations as configured
|
|
by the netlink configuration interface known e.g. from iptables.
