commit c6dde8ffd071aea9d1ce64279178e470977b235c upstream. The current channel-map control implementation in USB-audio driver may lead to an error message like "control 3:0:0:Playback Channel Map:0: access overflow" when CONFIG_SND_CTL_VALIDATION is set. It's because the chmap get callback clears the whole array no matter which count is set, and rather the false-positive detection. This patch fixes the problem by clearing only the needed array range at usb_chmap_ctl_get().
