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/'

config RAS_CEC
bool "Correctable Errors Collector"
depends on X86_MCE && MEMORY_FAILURE && DEBUG_FS
help
This is a small cache which collects correctable memory errors per 4K
page PFN and counts their repeated occurrence. Once the counter for a
PFN overflows, we try to soft-offline that page as we take it to mean
that it has reached a relatively high error count and would probably
be best if we don't use it anymore.
Bear in mind that this is absolutely useless if your platform doesn't
have ECC DIMMs and doesn't have DRAM ECC checking enabled in the BIOS.
config RAS_CEC_DEBUG
bool "CEC debugging machinery"

depends on RAS_CEC
help
Add extra files to (debugfs)/ras/cec to test the correctable error
collector feature. "pfn" is a writable file that allows user to
simulate an error in a particular page frame. "array" is a read-only
file that dumps out the current state of all pages logged so far.
