v7 follows as its own thread. > What patch format is this? How did you submit it? A hand-rolled Python SMTP script, which is as ill-advised as it sounds. v7 goes out with git send-email, so the format is the standard one from here on. > If the SCSI DH the right approach here? It is unusual, and it was a pragmatic out-of-tree choice rather than a design statement. The enclosure exposes a single mass-storage interface that usb-storage owns, so a USB interface driver cannot claim it without taking the disk down with it, and hooking the SCSI bus from a module is not possible without the unexported scsi_bus_type. The device handler was the one hook that observes the sdev without claiming it, which keeps the enclosure a normal block device. For in-tree the plan is the split mentioned in the v6 cover letter: the SCSI attachment moves under drivers/scsi (notifier or an exported attach helper, whichever the SCSI side prefers) and the LED part stays in drivers/leds. Happy to rework the attachment in whichever form you and the SCSI folks prefer. > Shouldn't this live in drivers/leds/rgb ? Yes. v7 moves it to drivers/leds/rgb/leds-asus-aura-scsi.c. It still has no Kconfig wiring; it is the verified out-of-tree module posted for the API discussion, as the commit message notes.
