From 96d4b8e1ad8a34711ef416dd61e6b60df9e12d30 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Thu, 1 Dec 2022 19:34:44 +0100 Subject: [PATCH] PM: sleep: Refine error message in try_to_freeze_tasks() A previous change amended try_to_freeze_tasks() with the "what" variable pointing to a string describing the group of tasks subject to the freezing which may be used in the error message in there too, so make that happen. Accordingly, update sleepgraph.py to catch the modified error message as appropriate. Signed-off-by: Rafael J.
