+ * @c: i2c_client struct representing this device
+ * @sd: our V4L2 sub-device
+ * @hdl: our V4L2 control handler
+ * @volume: audio volume V4L2 control (non-cx2583x devices only)
+ * @mute: audio mute V4L2 control (non-cx2583x devices only)
+ * @pvr150_workaround: whether we enable workaround for Hauppauge PVR150
+ * hardware bug (audio dropping out)
+ * @radio: set if we are currently in the radio mode, otherwise
+ * the current mode is non-radio (that is, video)
+ * @std: currently set video standard
+ * @vid_input: currently set video input
+ * @aud_input: currently set audio input
+ * @audclk_freq: currently set audio sample rate
+ * @audmode: currently set audio mode (when in non-radio mode)
+ * @vbi_line_offset: vbi line number offset
+ * @id: exact device model
+ * @rev: raw device id read from the chip
+ * @is_initialized: whether we have already loaded firmware into the chip
+ * and initialized it
+ * @vbi_regs_offset: offset of vbi regs
+ * @fw_wait: wait queue to wake an initalization function up when
+ * firmware loading (on a separate workqueue) finishes
+ * @fw_work: a work that actually loads the firmware on a separate
+ * workqueue
+ * @ir_state: a pointer to chip IR controller private data
+ * @pads: array of supported chip pads (currently only a stub)
