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 common code can be better reused
at the end of this function.

This issue was detected by using the Coccinelle software.
