From: Krzysztof Helt <krzysztof.h1@xxxxx>
This patch adds additional check for OPL3 device. I found that PNP
region returned
by the card is 0x380 - 0x38f but the OPL3 device is located at 0x388
(standard FM
device address). The driver checks start of the range (0x380) which is
incorrect.

The same problem appears on two cards I have with Opti chipset:
opti931 and opti933.
If someone can test if the opti92x PnP has the same problem I would be grateful.
Regards,
Krzysztof
