[PATCH net-next] net: ipconfig: Remove outdated comment and indent code block
Posted by Thorsten Blum 1 month, 2 weeks ago
The comment has been around ever since commit 1da177e4c3f4
("Linux-2.6.12-rc2") and can be removed. Remove it and indent the code
block accordingly.

## Form letter - net-next-closed

The net-next tree is closed for new drivers, features, code refactoring
and optimizations due to the merge window and the winter break. We are
currently accepting bug fixes only.

Please repost when net-next reopens after Jan 2nd.

RFC patches sent for review only are obviously welcome at any time.
