Prarit Bhargava 16b7c275c0 tools: cpupower: fix return checks for sysfs_get_idlestate_count() ... Red Hat and Fedora use a bug reporting tool that gathers data about "broken" systems called sosreport. Among other things, it includes the output of 'cpupower idle-info'. Executing 'cpupower idle-info' on a system that has cpuidle disabled via 'cpuidle.off=1' results in a 300 second hang in the cpupower application. ie) [root@intel-brickland-05]# cpupower idle-info Could not determine cpuidle driver Analyzing CPU 0: Number of idle states: -19 [hang] The problem is that the cpupower code only checks for a zero return from sysfs_get_idlestate_count(). The function can return -ENODEV (-19) as above. This patch fixes callers to sysfs_get_idlestate_count() to check the right return values.
