    Subject[PATCH 5.18 35/67] ALSA: usb-audio: Add missing ep_idx in fixed EP quirks
    Date
    From: Takashi Iwai <tiwai@suse.de>

    commit 7b0efea4baf02f5e2f89e5f9b75ef891571b45f1 upstream.

    The quirk entry for Focusrite Saffire 6 had no proper ep_idx for the
    capture endpoint, and this confused the driver, resulting in the
    broken sound. This patch adds the missing ep_idx in the entry.

    While we are at it, a couple of other entries (for Digidesign MBox and
    MOTU MicroBook II) seem to have the same problem, and those are
    covered as well.

    Fixes: bf6313a0ff76 ("ALSA: usb-audio: Refactor endpoint management")
