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/'

If you have a TPM security chip in your system, which
|
|
implements the Trusted Computing Group's specification,
|
|
say Yes and it will be accessible from within Linux. For
|
|
more information see <http://www.trustedcomputinggroup.org>.
|
|
An implementation of the Trusted Software Stack (TSS), the
|
|
userspace enablement piece of the specification, can be
|
|
obtained at: <http://sourceforge.net/projects/trousers>. To
|
|
compile this driver as a module, choose M here; the module
|
|
will be called tpm. If unsure, say N.
|
|
Notes:
|
|
1) For more TPM drivers enable CONFIG_PNP, CONFIG_ACPI
|
|
and CONFIG_PNPACPI.
|
|
2) Without ACPI enabled, the BIOS event log won't be accessible,
|
|
which is required to validate the PCR 0-7 values.

This setting exposes the TPM's Random Number Generator as a hwrng
