So, errors can also The warning is due to comment quote by BLG, which is separated by a dash line above. While it is fine in the docbook days, current documentation framework (Sphinx + kernel-doc) complains about it, so the documentation for __dev_queue_xmit() is not generated. The commit containing the quote is actually d29f749e252bcd ("net: Fix build failure with 'make mandocs'."), which interacts with commit c526fd8f9f4f21 ("net: inline dev_queue_xmit()") that Stephen reported. Fix the warning by removing the quote and adjust the method documentation accordingly. Fixes: d29f749e252bcd ("net: Fix build failure with 'make mandocs'.")
