86e27cdbf1 hctl: Remove a useless assert 
The case where the element is unavailable (for example gone away since
the event was created) is handled beneath.

03388ca6d3 Mark static tables as constant when possible. 
This makes it possible to write them to .data.rel.ro or to .rodata if
there is no relocation involved (arrays of character arrays).

2a7f35347b Make snd_hctl_wait() respect the API 
snd_hctl_wait() currently makes a lot of assumptions that fall outside
the defined API. snd_pcm_wait(), however, follows the API nicely so the
new version is based on that.
