commit 3b322323d036ae2fc9f685bfc74d1ebcd5532159
Author: Raphael Kubo da Costa <rakuco@FreeBSD.org>

    alsa: Relax ALSA version checks for 1.1.x to be detected.

    Relax the check for SND_LIB_MINOR and SND_LIB_SUBMINOR so that ALSA
    1.1.x is not considered older than 1.0.10. QtMultimedia builds fine with
    ALSA 1.1.
