Some comments on the patch header:
* No need to put v1 on a patch. If you are asked to revise it, then you can start with v2.
* sound: pci: ymfpci: ymfpci_main is not the proper subject line for this file. Do git log --oneline and see what others have done.
* There should not be a - after the final colon in the subject line.
* I'm not sure why I was included in this patch. get_maintainers by default gives the names of a lot of people. For general cleanup patches like this one, you can use the following options, that will just send the patch to the maintainers, and not to everyone who has ever touched the file:
scripts/get_maintainer.pl --nokeywords --nogit --nogit-fallback --norolestats
