[dm-devel] [PATCH]: dm-snap.c fix passing wrong type of argument

[Jonathan Brassow]

Perhaps the ordering could change a little, but from my point of view,
the following patches are prerequisites to this patch:
  1) dm-exception-store-introduce-registry.patch
  2) dm-exception-store-move-dm_target-pointer.patch
  3) dm-exception-store-move-chunk_fields.patch
  4) dm-exception-store-move-cow-pointer.patch
  5) dm-snapshot-remove-dm_snap-header-use.patch
  6) dm-snapshot-remove-dm_snap-header.patch
  7) dm-snapshot-use-DMEMIT-macro-for-status.patch
  8) dm-snapshot-move-ctr-parsing-to-exception-store.patch
  9) dm-snapshot-move-status-to-exception-store.patch
  10) dm-exception-store-generalize-table-args.patch
  11) dm-snapshot-new-ctr-table-format.patch
  12) dm-snapshot-cleanup.patch

The 'toupper' function returns an integer, but 'dm_exception_store_create'
takes a (char *).
