Now we may handle more than 32 cards, depending on Kconfig.

I can understand I should not use 'unsigned int' for bitmap of each card instances because in most architecture 'unsigned int' has just 32 bit width.

Use bitmap instead.

But I cannot understand this sentence.

I already use this 'devices_used' for bitmap. So I guess you did mean alternative ways like pointer array. For example: static struct snd_fireworks *devices_used[SNDRV_CARDS];

Can I request your explaination for this?

Thanks
