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.
