This patch is severely whitespace damaged. Can you fix your MUA
or try to use git-send-email?

The changelog as well is of low quality. Maybe something like this:

infiniband: cxgb4: fix memory skb memory leak

... would be better.

Also, this fails the build, due to the extra dot character after
the comment. :-(

Thanks,
