Re: [PATCH v2 0/5] MR5564: mmdevapi: Adjust timing in AudioClient_Initialize, removing related code from drivers.

```c
../dlls/winealsa.drv/alsa.c:88:29: error: 'min_period' defined but not used [-Werror=unused-const-variable=]
   88 | static const REFERENCE_TIME min_period = 50000;
      |                             ^~~~~~~~~~
```

@huw Should I change this to set the minimum period like the other backends do?
