[PATCH 15/25] mciseq: Fix some MCIERROR_* codes (related to auto-open).

[Joerg-Cyril.Hoehle at t-systems.com]

Hi,

MCI compound file drivers should recognize 3 modes of operation:
1. Open sequencer or waveaudio
 => only Capability and some Info flags are supported
2. Open with non-empty file name
3. Open with empty name for recording

+    if (wmm->hFile == 0)	return MCIERR_UNSUPPORTED_FUNCTION;
This looks like nothing but ensures compatible behaviour in mode 1.
It has an added benefit: with nearly all commands (even Stop!) unsupported
when the driver is opened without valid file, checks for uninitialized slots
become mostly superfluous.

Regards,
	Jörg Höhle
