Now I'm not fully understand what you mean. This patch series does not 
remove ALPS_PROTO_V4 support. Just move ALPS_PROTO_V4 out of 
alps_model_info table structure (same as for V1 and V6). Field 
command_mode_resp is removed from alps_model_info, but that can be done 
only because command_mode_resp is used by ALPS_PROTO_V4 (which is moved 
out of alps_model_info).

So I do not understand why do you think moving ALPS_PROTO_V4 out of 
alps_model_info is good, but ALPS_PROTO_V6 or ALPS_PROTO_V1 not.
