Subject: drm/i915: Mark i915.reset as unsigned
Git-commit: aae970d8454bb9b6b15f385250027af4c454d4f4
Patch-mainline: v5.7-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
We have been using '-1' to mean the maximum i915.reset level in the
belief that it was unsigned... This turns out to have been a grave
error, and instead of setting the default reset mechanism in igt,
we have been disabling reset!
