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.
It's a proof showing that people are just too lazy and copy the first implementation pattern :)
Thus, if you insist, I can do it, but my vote is "it doesn't worth of doing it at all".
Well, I'm not insisting to change that, but I still think that your argument is rather weak from the code quality POV.
The C99 style initialization is definitely an improvement for understanding the code. The most important question is not about how often changing the code, but about how better a reader can understand and how it give less errors.
In general I certainly agree with you. In this particular case uglification vs. clearness not in the right balance (to me at least).
It results in more lines? Yes. It's uglier? Depends. So what? It makes clearer and less error-prone.
Again, above case one has to file all members no matter what, since it's a mapping and explicit better than implicit there. Taking above into consideration the C99 style just adds a noise here for my POV.
Hrm, must I do that? No, it's still a kind of matter of taste.
So, let's agree not to touch this particular case(s)?
Yeah, that implies it, I don't mind too much details.
thanks,
Takashi
