Revision 883a1d49f0d77d30012f114b2e19fc141beb3e8e authored by Lars-Peter Clausen on 18 June 2014, 11:32:35 UTC, committed by Takashi Iwai on 18 June 2014, 13:13:37 UTC
The ALSA control code expects that the range of assigned indices to a control is
continuous and does not overflow. Currently there are no checks to enforce this.
If a control with a overflowing index range is created that control becomes
effectively inaccessible and unremovable since snd_ctl_find_id() will not be
able to find it. This patch adds a check that makes sure that controls with a
overflowing index range can not be created.
