Subject: checkpatch: add test for repeated words
Try to avoid adding repeated words either on the same line or consecutive
comment lines in a block
e.g.:
duplicated word in comment block
/*
* this is a comment block where the last word of the previous
* previous line is also the first word of the next line
*/
and simple duplication
/* test this this again */
