The driver was introduced in 2.6.11 in the pre-git times with commit
"[PATCH] mips: vR41xx updates". However, even back then, this driver
was not able to be compiled, as a number of udpates had been missing
from this driver: It still provided a "->get_io_map" callback (removed
for v2.5.66) and a "->inquire_socket" callback and used socket_cap_t
(removed for v2.5.72). Moreover, this driver failed to be brought and
be kept up to date; e.g. it still provides '->register_callback',
incompatible with a change committed for v2.6.14 in
commit 7f316b033b36 ("[PATCH] pcmcia: remove socket register_callback"),
and uses INIT_WORK() with three arguments which was removed in
commit 65f27f38446e1 ("WorkStruct: Pass the work_struct pointer instead
of context data")

'status' is known to be 0 at this point. It must be set to a meaningful
value in order to return an error code if one of the 'of_get_property()'
call fails.

Return -EINVAL in such a case.

struct at91_cf_data is only used in the driver since all the platforms moved
to device tree, move its definition locally.

This value is only used by a PCMCIA driver and not very useful.

Replace the existing /* fall through */ comments and its variants with
the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary
fall-through markings when it is the case.

Since commit 84af7a6194e4 ("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/'
