[PATCH 2/8] media: atmel-isi: use 'time_left' variable with wait_for_completion_timeout()
From: Wolfram Sang
Date: Mon Jun 03 2024 - 05:29:26 EST
There is a confusing pattern in the kernel to use a variable named 'timeout' to
store the result of wait_for_completion_timeout() causing patterns like:
timeout = wait_for_completion_timeout(...)
if (!timeout) return -ETIMEDOUT;
with all kinds of permutations. Use 'time_left' as a variable to make the code
self explaining.
