Subject: drm/komeda: add rate limiting disable to err_verbosity
Git-commit: f8fbe33be7b61b180e340c01af6d911f503d3fc1
Patch-mainline: v5.6-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
It's possible to get multiple events in a single frame/flip, so add an
option to print them all.
