[igt-dev] [PATCH i-g-t 0/3] i915/i915_hwmon: General verification of hwmon attributes

[Ashutosh Dixit <ashutosh.dixit@intel.com>]

Ensure we can read all hwmon attributes. For writable attributes, also
ensure the read value approximately matches the written value, taking the
clamping of writes into account.

v2: Added new patch "lib/igt_sysfs: Make it easier to extend verification
    of clamped sysfs attr". No changes to previous patches.
v3: Identical to v2, failed to copy reviewers
v4: Drop the concept of a 'clamped' sysfs attribute, it is not
    necessary. All we need is a writable attribute for which the read
    values will match the written values for a few points across the range
    of all possible values.
v5: Dropped function rw_attr_reverify_points since it was repeating the
    verification already done during the sweep so has limited utility. This
    results in simplifying the code even more.
