From 38935f3366801355ac64731d8df1c6bb5d6609ee Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Tue, 4 Jun 2024 23:27:31 +0200 Subject: usb: typec: tcpm: use 'time_left' variable with wait_for_completion_timeout() 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.
