There is a confusing pattern in the kernel to use a variable named 'timeout' to store the result of wait_for_completion_interruptible_timeout() causing patterns like:
timeout = wait_for_completion_interruptible_timeout(...) if (!timeout) return -ETIMEDOUT;
with all kinds of permutations. Use 'time_left' as a variable to make the code self explaining.
