Original commit message from CVS:
* sys/sunaudio/gstsunaudiosrc.c: (gst_sunaudiosrc_open):
Apply patch to open the mixer control and set the MULTIPLE_OPEN
ioctl. On solaris, the mixer device doesn't need opening non-blocking
- it can be opened by multiple processes by default, but needs the ioctl 	for multiple opens within 1 process.
Patch by: Jerry Tan <jerry.tan at sun dot com>
Fixes: #349015
