The ax25_dev is managed by reference counting, so it should not be
deallocated directly by kfree() in ax25_dev_free(), replace it with
ax25_dev_put() instead.

You repeated a wording mistake in the summary phrase from a previous cover letter.
Please avoid confusion about desired code replacements.
How do you think about to append parentheses to involved function names?


Would you find the following change description a bit nicer?

   The object “ax25_dev” is managed by reference counting.
   Thus it should not be directly released by a kfree() call in ax25_dev_free().
   Replace it with a ax25_dev_put() call instead.


Would you like to extend patch version descriptions (or changelogs) accordingly?

Markus
