| |
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.
Please apply
