[PATCH] make i810_audio GETOSPACE consistent with i810_write()

[Tobias Diedrich]

Hi,

This fixes a bug in i810_ioctl(), which made the GETOSPACE ioctl return
a different value than that checked against in i810_write.

>From i810_write():
|                cnt = dmabuf->dmasize - dmabuf->fragsize - dmabuf->count;
|                // this is to make the copy_from_user simpler below
|                if(cnt > (dmabuf->dmasize - swptr))
|                        cnt = dmabuf->dmasize - swptr;
|                spin_unlock_irqrestore(&state->card->lock, flags);
|
|#ifdef DEBUG2
|                printk(KERN_INFO "i810_audio: i810_write: %d bytes available spa
|ce\n", cnt);
|#endif

where cnt is the space available.
