Subject: [PATCH] iommu/arm-smmu: Un-demote unhandled-fault msg
From: Rob Clark <robdclark@...omium.org>
Previously this was dev_err_ratelimited() but it got changed to a
ratelimited dev_dbg(). Change it back to dev_err().
Fixes: d525b0af0c3b ("iommu/arm-smmu: Pretty-print context fault related regs")
Signed-off-by: Rob Clark <robdclark@...omium.org>

We have crash telemetry watching for "Unhandled context fault", so we
want to preserve this error msg.
