[PATCH] ASR driver update

[Scott Long]

Thanks for the report.  This is fixed in rev 1.58 of asr.c.  I'm not
sure why I didn't see this before.  Btw, do you by chance have a
2005/2015 SO-DIMM form-factor card?  I'm having trouble with mine and
can't figure out if it's because the card is from a very early
pre-production sample.

Thanks,

Scott
