Hamish Martin 085d735c85 uio: Prevent device destruction while fds are open ...

commit a93e7b331568227500186a465fee3c2cb5dffd1f upstream.

Prevent destruction of a uio_device while user space apps hold open
file descriptors to that device. Further, access to the 'info' member
of the struct uio_device is protected by spinlock. This is to ensure
stale pointers to data not under control of the UIO subsystem are not
dereferenced.
