[PATCH 1/4] cpuidle - sysfs : change function parameter

2012-10-10 Thread Daniel Lezcano
The function needs the cpuidle_device which is initially passed to the caller. The current code gets the struct device from the struct cpuidle_device, pass it the cpuidle_add_sysfs function. This function calls per_cpu(cpuidle_devices, cpu) to get the cpuidle_device. This patch pass the cpuidle_d

The following patchset does some cleanup and prepares the place for the multiple driver support. We want to add an entry per cpu for the driver when the configuration defines the support for multiple cpuidle drivers. This patchset creates a single entry function for adding a cpuidle device to the
