[PATCH v2 0/2] MR2692: Draft: msi:custom: ok_() takes printf-style arguments.

[Francois Gouget (＠fgouget)]

custom.c does not use the test.h and debug.h definitions and presumably has a good reason not to. But this resulted in the printf-format compiler attribute getting lost. So copy it from debug.h to allow proper checks of the ok_() format string.

Also fix said format strings.
