H A Dxen_snd_front.cdiff 0d5bcfc9974ad8ce0fc77a95a53ab704faa0dfb7 Thu May 31 08:25:07 CEST 2018 Dan Carpenter <dan.carpenter@oracle.com> ALSA: xen-front: fix a loop timeout

We want the loop to exit when "to" is set to zero, but in the current
code it's set to -1. Also I tweaked the indenting so it doesn't look
like we're passing "--to" to xenbus_read_unsigned().
