strstrip strips whitespace from the beginning and end of a string. I agree you have to take the returned pointer if you want to strip from the beginning. However, if you wish to keep the whitespace at the beginning and only wish strstrip to remove it from the end, then it's entirely legitimate to discard the returned pointer. This is what we have in drivers/scsi/ipr.c and the patch to make strstrip __must_check is now causing SCSI spurious warnings in that code.
