Commit Message

  The struct bus_type pointer in hid_bpf_ops just passes the pointer to
the driver core, and the driver core can handle, and expects, a constant
pointer, so also make the pointer constant in hid_bpf_ops.

Part of the process of moving all usages of struct bus_type to be
constant to move them all to read-only memory.
