Subject[PATCH 8/8] iio: pressure: zpa2326: use 'time_left' variable with wait_for_completion_interruptible_timeout()
Date
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.
