Hi,

this contains two fixes for PCM OSS bugs that have been triggered by syzbot. These are simple and straightforward, and I'm going to queue for 4.15-rc8.

I tried to reproduce the issue as well with the reproducer generated by syzbot. But what syzbot reported was that the CPU didn't sleep for 140 seconds. But with a long write() we'll go to sleep in between frames. So when I tried the lockup detector never triggered.

Were you able to reproduce the same CPU lockup as syzbot?
