[PATCH v2 0/2] hwmon: (dell-smm) Improve ioctl handler

[Armin Wolf]

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

  hwmon: (dell-smm) Unify i8k_ioctl() and i8k_ioctl_unlocked()
