W/o your series applied (so line numbering might be slightly
different), checkpatch.pl says:

  ERROR: trailing whitespace
  #270: FILE: -:270:
  +^I * This do { } while() loop will get ALL chars out of Rx FIFO $

AFAICS, your patch [7/9] ("drivers: tty: 68328serial.c: remove trailing
whitespaces") doesn't fix this one.

In good old regexp tradition, the '$' sign denotes the end of line. So,
there is a single space after "FIFO" and before the end of line.

If you happen to be Emacs users, consider trying out whitespace-mode.
If not, try to find another way to make your editor visualize whitespace
somehow.
