When CONFIG_SND_SOC_ZL38060 is y, MODULE_DEVICE_TABLE expands to

so zl38_dt_ids will be unused. This is a pretty common construct in the
kernel and the only way I can think of to resolve this through the code
is by adding __used annotations to all of these variables, which I think
is overkill for this.
Personally, I think this warning should be downgraded to W=2,
thoughts?
We've had that warning available for ever, we shouldn't need to disable
it now. I had thought there was supposed to be magic which caused
of_match_ptr() to make things look referenced when !OF but don't seem to
actually see any sign of it. The other thing is to just have ifdefs
around the table.
