This patch series improves the ioctl handler in dell_smm_hwmon. The first patch is simplifying the ioctl handler by removing an unnecessary switch case, while the second patch is unifying both i8k_ioctl() and i8k_ioctl_unlocked(), resulting in better performance since i8k_mutex is only acquired when needed (during fan status change) instead of being acquired for every ioctl call.
Tested on a Dell Inspiron 3505.
changes in v2: - simplify logic between mutex_lock()/_unlock() - replace hardcoded values with sizeof statements
