When running 'make dt_binding_check' in tree after the 1st time, the generated example .dt.yaml files are mistakenly added to the list of schema files.

2019-07-22net/tls: fix transition through disconnect with closeJohn Fastabend1-0/+6
It is possible (via shutdown()) for TCP socks to go through TCP_CLOSE state via tcp_disconnect() without actually calling tcp_close which would then call the tls close callback. Because of this a user could disconnect a socket then put it in a LISTEN state which would break our assumptions about sockets always being ESTABLISHED state. More directly because close() can call unhash() and unhash is implemented by sockmap if a sockmap socket has TLS enabled we can incorrectly destroy the psock from unhash() and then call its close handler again. But because the psock (sockmap socket representation) is already destroyed we call close handler in sk->prot. However, in some cases (TLS BASE/BASE case) this will still point at the sockmap close handler resulting in a circular call and crash reported by syzbot. To fix both above issues implement the unhash() routine for TLS. v4: - add note about tls offload still needing the fix; - move sk_proto to the cold cache line; - split TX context free into "release" and "free", otherwise the GC work itself is in already freed memory; - more TX before RX for consistency; - reuse tls_ctx_free(); - schedule the GC work after we're done with context to avoid UAF; - don't set the unhash in all modes, all modes "inherit" TLS_BASE's callbacks anyway; - disable the unhash hook for TLS_HW.

2019-07-20dt-bindings: iio: ad7124: Fix dtc warnings in exampleRob Herring1-33/+38
With the conversion to DT schema, the examples are now compiled with dtc. The ad7124 binding example has the following warning: Documentation/devicetree/bindings/iio/adc/adi,ad7124.example.dts:19.11-21: \ Warning (reg_format): /example-0/adc@0:reg: property has invalid length (4 bytes) (#address-cells == 1, #size-cells == 1) There's a default #size-cells and #address-cells values of 1 for examples.
