Who is setting up this timer? This patch can also be done in userspace:
fd = open("/dev/rtc",...); ioctl(alsafd, RTCFD, fd);
in the alsa driver you can do:
file = fget(fd); ... if (file->f_op && file->f_op->ioctl) file->f_op->ioctl(file->f_dentry->d_inode, file, cmd, arg); ... fput(file);
bye, Roman
