OSS: soundcard: locking bug in sound_ioctl()
commit d4cfa4d12f46e2520f4c1d1a92e891ce068b7464 upstream.
We shouldn't return directly here because we're still holding the
&soundcard_mutex.
This bug goes all the way back to the start of git. It's strange that
no one has complained about it as a runtime bug.
