parenttools: cpupower: fix return checks for sysfs_get_idlestate_count() (diff)
Revert "tools: cpupower: fix return checks for sysfs_get_idlestate_count()"
This reverts commit 16b7c275c055cc36218404b5d147be7f76575087. My previous commit 16b7c275c055 ("tools: cpupower: fix return checks for sysfs_get_idlestate_count()") was not correct. After looking at the changelog for cpupower I noticed that Thomas had changed the return of sysfs_get_idlestate_count() to an unsigned int to simplify the code. The problem is really that both he (in his original change) and I (in my new change) missed the obvious that sysfs_get_idlestate_count() can't return -ENODEV. It should just return 0 for "no c-states". Fixes: 16b7c275c055 (tools: cpupower: fix return checks for ...) Signed-off-by: Prarit Bhargava <prarit@redhat.com> Signed-off-by: Rafael J.
