Reviewed-by: James Hogan <[email protected]> I think this is obviously correct, so it'd be great to squeeze it into 4.15 final. Fortunately the other related change, commit 664eadd6f44b ("bcma: Fix 'allmodconfig' and BCMA builds on MIPS targets"), already depends on MIPS so doesn't have the same issue. Sorry for the breakage!
