Yes.

It was for a minimization of churn.

    checkpatch: look for common misspellings
    
    Check for misspellings, based on Debian's lintian list.  Several false
    positives were removed, and several additional words added that were
    common in the kernel:
    
            backword backwords
            invalide valide
            recieves
            singed unsinged
    
    While going back and fixing existing spelling mistakes isn't a high
    priority, it'd be nice to try to catch them before they hit the tree.
