[PATCH 0/7] MR799: wineoss: Switch to mmdevapi's unixlib.h.

[Davide Beatrici (＠davidebeatrici)]

Follow-up to !600.

---

The version check logic is removed because redundant.

`SNDCTL_SYSINFO` was introduced in OSS 4.0: [oss4white.pdf](/uploads/e85c3196b611560db849cfac9e158bd2/oss4white.pdf)

The `ioctl()` call fails with OSS 3.x.
