Subject[PATCH net-next] net/core: Remove comment quote for __dev_queue_xmit()
Date
When merging net-next for linux-next tree, Stephen Rothwell reported
htmldocs warning:

Documentation/networking/kapi:92: net/core/dev.c:4101: WARNING: Missing matching underline for section title overline.

-----------------------------------------------------------------------------------
I notice this method can also return errors from the queue disciplines,
including NET_XMIT_DROP, which is a positive value. 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'.")
