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/'

infrastructure code to support RapidIO interconnect devices.

Amount of time a discovery node waits for a host to complete
enumeration before giving up.
config RAPIDIO_ENABLE_RX_TX_PORTS
bool "Enable RapidIO Input/Output Ports"
depends on RAPIDIO
help
The RapidIO specification describes a Output port transmit
enable and a Input port receive enable. The recommended state
for Input ports and Output ports should be disabled. When
this switch is set the RapidIO subsystem will enable all
ports for Input/Output direction to allow other traffic
than Maintenance transfers.

bool "DMA Engine support for RapidIO"
depends on RAPIDIO
select DMADEVICES
select DMA_ENGINE
help
Say Y here if you want to use DMA Engine frameork for RapidIO data
transfers to/from target RIO devices. RapidIO uses NREAD and
NWRITE (NWRITE_R, SWRITE) requests to transfer data between local
memory and memory on remote target device. You need a DMA controller
capable to perform data transfers to/from RapidIO.
If you are unsure about this, say Y here.

help
Say Y here if you want the RapidIO subsystem to produce a bunch of
debug messages to the system log. Select this if you are having a
problem with the RapidIO subsystem and want to see more of what is
going on.
If you are unsure about this, say N here.

There are different enumeration and discovery mechanisms offered
for RapidIO subsystem. You may select single built-in method or

Selecting a built-in method disables use of loadable methods.
If unsure, select Basic built-in.
