Masahiro Yamada a7f7f6248d treewide: replace '---help---' in Kconfig files with 'help'
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 "PPS support"
help
PPS (Pulse Per Second) is a special pulse provided by some GPS
antennae. Userland can use it to get a high-precision time
reference.
Some antennae's PPS signals are connected with the CD (Carrier
Detect) pin of the serial line they use to communicate with the
host. In this case use the SERIAL_LINE client support.
Some antennae's PPS signals are connected with some special host
inputs so you have to enable the corresponding client support.
To compile this driver as a module, choose M here: the module
will be called pps_core.ko.
if PPS
config PPS_DEBUG
bool "PPS debugging messages"
help
Say Y here if you want the PPS support to produce a bunch of debug
messages to the system log. Select this if you are having a
problem with PPS support and want to see more of what is going on.
config NTP_PPS
bool "PPS kernel consumer support"
depends on !NO_HZ_COMMON
help
This option adds support for direct in-kernel time
synchronization using an external PPS signal.
It doesn't work on tickless systems at the moment.
