Subject: [PATCH 0/2] firmware: cs_dsp: Remove need for clients to supply dummy cs_dsp_client_ops

Clients of cs_dsp can provide optional callback function pointers, in
a struct cs_dsp_client_ops. The client had to provide a pointer to a
struct even if it didn't implement any of the callbacks.

Commit 1 in this series changes that so the client doesn't have to
provide a dummy struct.

Commit 2 adds kunit tests cases for this.

Richard Fitzgerald (2):
  firmware: cs_dsp: Don't require client to provide a struct
    cs_dsp_client_ops
  firmware: cs_dsp: Add test cases for client_ops == NULL
