[PATCH] driver-core: don't free devt_attr till the device is released
Currently, devt_attr for the "dev" file is freed immediately on device
removal, but if the "dev" sysfs file is open when a device is removed,
sysfs will access its attribute structure for further access including
close resulting in jumping to garbled address. Fix it by postponing
freeing devt_attr to device release time.
Note that devt_attr for class_device is already freed on release.
This bug is reported by Chris Rankin as bugzilla bug#8198.
