Subjectdouble unlock in rng_dev_read()
It seems like we unlock rng_mutex twice (2.6.33-rc1).

drivers/char/hw_random/core.c
151 mutex_unlock(&rng_mutex);
152
153 if (need_resched())
154 schedule_timeout_interruptible(1);
155
156 if (signal_pending(current)) {
157 err = -ERESTARTSYS;
158 goto out;
159 }
160 }
161 out_unlock:
162 mutex_unlock(&rng_mutex);

regards,
dan carpenter
