+ * struct cx25840_state - a device instance private data
+ * @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)
