Subject: IDE: Unregister and disable devices if initialization fails.
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=51d6ac7011cc354eade4f1282857947930a905aa;p=openwrt%2Fstaging%2Fblogic.git

IDE: Unregister and disable devices if initialization fails.

On reboot the loop in device_shutdown gets confused by these partially
initialized devices and goes into an infinite loop. Therefore unregister
and disable these devices.
