[ Upstream commit 1c801e7f77445bc56e5e1fec6191fd4503534787 ]
Some time ago, we introduced the obey_preferred_dacs flag for choosing the DAC/pin pairs specified by the driver instead of parsing the paths. This works as expected, per se, but there have been a few cases where we forgot to set this flag while preferred_dacs table is already set up. It ended up with incorrect wiring and made us wondering why it doesn't work.
Basically, when the preferred_dacs table is provided, it means that the driver really wants to wire up to follow that. That is, the presence of the preferred_dacs table itself is already a "do-it" flag.
In this patch, we simply replace the evaluation of obey_preferred_dacs flag with the presence of preferred_dacs table for fixing the misbehavior. Another patch to drop of the obsoleted flag will follow.
