From: "Matthew R. Ochs" <[email protected]> Validation statements to enforce assumptions about specific defines are not being evaluated by the compiler due to the fact that they reside in a routine that is not used. To activate them, call the routine as part of module initialization. As an additional, related cleanup, remove the now-defunct CXLFLASH_NUM_CMDS.
