[PATCH 21/29] mac_scsi: Convert to platform device

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Convert mac_scsi to platform device and eliminate scsi_register().

Platform resources for chip registers now follow the documentation. This
should fix issues with the Mac IIci (and possibly other models too).

Signed-off-by: Finn Thain <fthain@xxxxxxxxxxxxxxxxxxx>

---

The new hwreg_present() call is not protected by local_irq_save/restore.
This assumes Geert's patch, "Disable/restore interrupts in
hwreg_present()/hwreg_write()":
