It has double conversion there:
1. LE CPU: Read as LE and converted to LE (no-op), so, just u16
2. BE CPU: Read as BE and converted to LE, makes it __le16
Looks like the conversion is not needed, only get_unaligned() is necessary.
P.S. What about lines 244-245 there? I think they are no-op.
Interesting that those two parts were added in quite different
