Two update suggestions were taken into account
from static source code analysis.

Markus Elfring (2):
  Use common code in hdsp_get_iobox_version()
  Use common error handling code in snd_hdspm_probe()

Add a jump target so that a bit of exception handling can be better reused
at the end of this function.

This issue was detected by using the Coccinelle software.

The subject prefix isn't right, it's about hdspm driver.
I applied the patch with that correction now.


thanks,
