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