Even on 3620, not all cmds switch to wcn36xx_smd_rsp_status_check_v2. And I don't think wcn36xx_smd_rsp_status_check_v2 should bind to 3620 (it may be related with firmware). In patch v2, the wcn36xx_smd_rsp_status_check_v2 is not bind to 3620. If you could test on none-3620 platform (I don't have none-3620 plafrom), that will be great. I will send out patch v2 soon which drive the build error and the comments from you. Thanks a lot for reviewing.

It confirm my thought that the change sticks to new firmware instead of specific platform. But we couldn't tell which version of firmware need this new format. Andy's original change has two conditions to use the new format: 1. The platform is 3620. - this should be removed because you need the same change for 3680. And patch v2 already remove it. 2. The packet size from firmware is larger than old response size. I suppose this one works in most case.

And I want to know whether the change from Andy could work on the platform which is using v1. Can you try this change on your platform? Thanks.
