2.7.4

v2 
 -tried to fix summary and commit message
v3
 -actually fixed summary and commit message
 -CCed staging mailing list

This looks good except that you now dropped the changelog again (what changed in v2 and v3?), and you CC:d the linux-next rather than the staging list [email protected] (I included the address in my response to v1).

You can use scripts/get_maintainer.pl on a patch to figure out which parties and lists to CC (you don't need to include LKML in this case).

Since you're doing this to learn the process, you can send a v4 and get everything right.

Thanks,
Johan
