Re: [alsa-devel] Question about card names

29 May 2019


      Hi
...
for (i = 0; i < ARRAY_SIZE(card->snd_card->driver); i++) {
	switch (card->snd_card->driver[i]) {

x=>			case '_':
x=>			case '-':
   		case '\0':
   			break;
   		default:
   			if (!isalnum(card->snd_card->driver[i]))
4=>					card->snd_card->driver[i] = '_';
   			break;
   		}
(snip)
...
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".
Is this bug ??
Grr
This break is for "switch", not for "for"...
Thank you for your help !!
Best regards
