pvrusb2: Implement reporting of connected sub-devices
From: Mike Isely <isely@pobox.com>
The pvrusb2 driver has a function that reports internal state. It can
be accessed from either the debug interface or as the result of a v4l
log status request. This change adds information listing sub-devices
to the report.
Priority: normal
