Hi
snd_soc_instantiate_card() setups card->snd_card's "shortname", "longname", "driver" names. (= 1,2,3).
But, it cares only card->snd_card->driver (= 4). I think we need to care about all naming, but why only driver ??
Do you mean the normalization of strings, or do you suggest to make mandatory? The normalization isn't needed for other name strings. The driver name is somewhat special, as it's used as a key for searches in the user-space.
Ahh, OK, I see. Thank you for clearing it. I want to have this explain at there (= I will post it, soon)
And, it seems in this loop, it breaks check if it finds "_" or "-" (= x). If my understanding was correct, the naming "abcd??efg" will be fixed to "abcd__efg", but, it do nothing if name was for example "-abcd??efg".
We do replace the two '?' in the latter case, too. It's a break statement in a switch block, i.e. just skip the case.
Thanks. My head is very spaghetting now...
Thank you for your help !! Best regards --- Kuninori Morimoto
