Better to use C99 style init?
Here it makes a little advantage over more uglified code.
I'm not always a fan of it, but this seems deserving. From the above, it's difficult to know which zero is for what.
I'm not sure it makes sense. Those fields are filed according to ACPI specification and applies to the platform in question. Usually you don't need to look into them on regular basis, perhaps one time per each platform which uses such combination of SoC + ASoC + Codec which is quite unlikely to be more than once twice per year(?).
So, for over few dozens of drivers which are using GPIO ACPI mapping tables this is the first request like this I see.
Thus, if you insist, I can do it, but my vote is "it doesn't worth of doing it at all".
