From 531a185d549e1c6225d7e1e553ba1c14dc391d69 Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Tue, 4 Jun 2024 23:22:37 +0200 Subject: [PATCH] misc: bh1770glc: use 'time_left' variable with wait_event_interruptible_timeout() There is a confusing pattern in the kernel to use a variable named 'timeout' to store the result of wait_event_interruptible_timeout() causing patterns like: timeout = wait_event_interruptible_timeout(...) if (!timeout) return -ETIMEDOUT; with all kinds of permutations. Use 'time_left' as a variable to make the code self explaining.
