Subject: [PATCH][next] ALSA: bebob: Fix bit flag quirk constants

From: Colin Ian King <colin.king@...onical.com>

The quirking bit-flags are currently set as contiguous integer enum values
and so currently SND_BEBOB_QUIRK_INITIAL_DISCONTINUOUS_DBC is zero and so
he quirking never getting set or tested correctly for this quirk. Fix this
by setting the quirking constants as shifted bit values.

Addresses-Coverity: ("Bitwise-and with zero")
Fixes: 93cd12d6e88a ("ALSA: bebob: code refactoring for model-dependent quirks")
Signed-off-by: Colin Ian King <colin.king@...onical.com>
