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/'

PPS support configuration

menuconfig PPS 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.
