-    <para>For driver debugging purposes this ioctl allows test
-applications to query the driver about the chips present on the TV

-specific bug, please contact the linux-media mailing list (&v4l-ml;)

-this structure. On success the driver stores information about the
-selected chip in the <structfield>ident</structfield> and
-<structfield>revision</structfield> fields. On failure the structure
-remains unchanged.</para>
-

-incrementing <structfield>match.addr</structfield> by one until
-<constant>VIDIOC_DBG_G_CHIP_IDENT</constant> fails with an &EINVAL;.
-The number zero always selects the host chip, &eg; the chip connected

-this chip.</para>
-
-    <para>When the driver could not identify the selected chip,
-<structfield>ident</structfield> will contain
-<constant>V4L2_IDENT_UNKNOWN</constant>. When no chip matched
-the ioctl will succeed but the
-<structfield>ident</structfield> field will contain
