[PATCH 0/6] dell-smm-hwmon fixes

[Pali RohÃr]

I'm sending all my dell-smm-hwmon patches in one series, because due to
changes in code other patches depends on previous.

First two patches fixes problem with old /proc/i8k file. Second is security
fix and should be backported to all stable kernels (that problem was there
always). I tested i8kctl tool (from i8kutils package) that it still works
with these patches. Without root access for those security operations just
showes '?' or '-1'.

Third and fourth patches try to fix problem on machines with broken
SMM/BIOS when calling function fan_type().

Fifth is new feature and last sixth useful for debugging.

Pali RohÃr (6):
  hwmon: (dell-smm) Fail in ioctl I8K_BIOS_VERSION when bios version is
    not a number
  hwmon: (dell-smm) Restrict fan control and serial number to
    CAP_SYS_ADMIN by default
  hwmon: (dell-smm) Disallow fan_type() calls on broken machines
  hwmon: (dell-smm) Cache fan_type() calls and change fan detection
  hwmon: (dell-smm) Detect fan with index=2
  hwmon: (dell-smm) In debug mode log duration of SMM calls
