Hello,

Very much appreciate the input. I admit that at first #1 made me think 
it's OK to change the name for the two but the later portion of the 
message (#2 and onward) made me think otherwise. Decided to not that 
change part of current series in v2, will send module renames as 
separate two patches either today or later this week - if 
snd_soc_sst_broadwell rename is not welcome, it won't get merged.
