* 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)
