This reverts commit 16b7c275. My previous commit 16b7c275 ("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: 16b7c275 (tools: cpupower: fix return checks for ...) Signed-off-by:
