[PATCH] dsound: do not allow adding a NULL ptr as buffer in DirectSoundDevice_AddBuffer()

[Pierre Schweitzer]

Dear all,

Please find attach a patch which prevents DirectSoundDevice_AddBuffer()
from accepting NULL pointers.
It results from a bugfix & testing here. While trying to start Steam
Lego Star Wars, I was experiencing an invalid address dereference in
DSOUND_ChangeListener() (line 312).

Adding this check makes the game work properly (with sound). I tested it.

Cheers,
