media: bpf: add bpf function to report mouse movement
Some IR remotes have a directional pad or other pointer-like thing that can be used as a mouse. Make it possible to decode these types of IR protocols in BPF. Cc: netdev@vger.kernel.org Signed-off-by: Sean Young <sean@mess.org> Signed-off-by: Alexei Starovoitov <ast@kernel.org>
