OK. I will rename the topic in v2.

In the patch series, [PATCH 1/5] divides ADDA_BE into UL_SRC_BE and
DL_SRC_BE. I was going to replace the link name, but I found it
shouldn't be configured for the machine, because mt6359 is the only
codec for ADDA_BE and it's hardcoded in the machine driver. As a
result, I decided to remove it.

I will separate it from the patch, and put the new patch after [PATCH
1/5].

Thanks,
