Commit Message

There are no hwmon selftests so there is no need to enable hwmon for
selftests. So enable hwmon only for real driver load.

v2: Move the logic inside i915_hwmon.c
v3: Move is_i915_selftest definition to i915_selftest.h (Badal)
v4: s/is_i915_selftest/is_i915_selftest_module/

 /* Using the i915_selftest_ prefix becomes a little unwieldy with the helpers.
