From 87602aeb8ad5bb1b2e23285a9d1322ac033f86c9 Mon Sep 17 00:00:00 2001 From: Daniel Lezcano Date: Sun, 14 Mar 2021 12:13:33 +0100 Subject: [PATCH] thermal/drivers/cpufreq_cooling: Remove unused list There is a list with the purpose of grouping the cpufreq cooling device together as described in the comments but actually it is unused, the code evolved since 2012 and the list was no longer needed. Delete the remaining unused list related code.
