[alsa-devel] Patch for alsa-info.sh

[Travis Place]

The below patch should stop alsa-info.sh from running amixer on cards that 
dont exist (ie, if the user has no card0, but has a card1)
I realise its a generally a rare case, and cards are _usually_ consecutive, 
but we might aswell cover all bases if we can.
