Did you actually compile and test this?  :)

add a comment /* fall through */ here

Just leave the comment as is.  You made it worse:

* if ata_device_add() returns zero, then everything is OK.

* if ata_device_add() returns non-zero, then an error occured. 
kfree(hp) is but one of several things that need to be cleaned up on 
failure.


Finally, please fix the format of your subject line per
	http://linux.yyz.us/patch-format.html

Most notably, each Subject should be unique for each patch.  e.g.

[PATCH 1/3] sata_promise: fix hotplug register offset
[PATCH 2/3] libata: add device hotplug infrastructure
[PATCH 3/3] sata_promise: add device hotplug support
