ALSA: bebob: use more identical mod_alias for Saffire Pro 10 I/O against Liquid Saffire 56
ALSA bebob driver has an entry for Focusrite Saffire Pro 10 I/O. The
entry matches vendor_id in root directory and model_id in unit
directory of configuration ROM for IEEE 1394 bus.
On the other hand, configuration ROM of Focusrite Liquid Saffire 56
has the same vendor_id and model_id. This device is an application of
TCAT Dice (TCD2220 a.k.a Dice Jr.) however ALSA bebob driver can be
bound to it randomly instead of ALSA dice driver. At present, drivers
in ALSA firewire stack can not handle this situation appropriately.
This commit uses more identical mod_alias for Focusrite Saffire Pro 10
I/O in ALSA bebob driver.
