Revision 392370e7aa387185349946d29a0e17b918e51ae6 authored by Krzysztof Mazur on 11 January 2013, 22:20:09 UTC, committed by Rafael J. Wysocki on 11 January 2013, 22:20:09 UTC
Commit bf4d1b5ddb78f86078ac6ae0415802d5f0c68f92 (cpuidle: support multiple drivers) changed the number of initialized state kobjects in cpuidle_add_state_sysfs() from device->state_count to drv->state_count, but left device->state_count in cpuidle_remove_state_sysfs(). The values of these two fields may be different, in which case a NULL pointer dereference may happen in cpuidle_remove_state_sysfs(), for example. Fix this problem by making cpuidle_add_state_sysfs() use device->state_count too (which restores the original behavior of it).
