However, it would fail to detect an existing control whose count is smaller than the new control's count and whose interval of IDs is entirely contained in the interval of the new control's IDs. To fix this, use the correct formula to detect overlapping intervals, which happens to simplify the condition. This problem was not encountered so far because ALSA does not yet allow drivers to allocate specific control IDs. Signed-off-by: Clemens Ladisch Signed-off-by: Takashi Iwai å
