Sure, you can re-spin the patch.

At that point of time I didn't think grouping phy drivers for each vendor is
required. But especially after [1] where I failed to notice an existing phy
driver can be reused and later has to be reverted. This could have been easily
identified by MAINTAINERS of that particular platform. That's why now I feel
grouping phy drivers and having a MAINTAINER for every vendor directory will
help to identify such issues.

Thanks
