ctxfi stores the Line Capture Switch and Mic Capture Switch controls in a file-scope kctls[] array so do_line_mic_switch() can notify the opposite control when the shared line/mic input selection changes. That storage is shared by all ctxfi cards. If more than one X-Fi card is present, a later card can overwrite the pointers saved by an earlier one. A control update on one card can then use another card's kcontrol object for snd_ctl_notify(). If that other card is removed, the saved pointer can also become stale. Store those notification targets in struct ct_mixer instead. The mixer is per-card state and matches the lifetime of the controls created for that card.
