Issue
from here
48 struct snd_card *snd_cards[SNDRV_CARDS];
49 EXPORT_SYMBOL(snd_cards);
I am not getting whats the meaning of it and why that is used. I tried to search about it but not understanding the meaning of that.
Solution
It makes a symbol accessible to dynamically loaded modules (provided that said modules add an extern declaration).
Not long ago, someone asked how to use it.
