[ Upstream commit fbf740aeb86a4fe82ad158d26d711f2f3be79b3e ]
In register_device, the return value of ida_simple_get is unchecked,
in witch ida_simple_get will use an invalid index value.
To address this issue, index should be checked after ida_simple_get. When
the index value is abnormal, a warning message should be printed, the port
should be dropped, and the value should be recorded.
Fixes: 9a69645dde11 ("ppdev: fix registering same device name")
