Revision 66cb3a2d7ad0d0e9af4d3430a4f2a32ffb9ac098 authored by David Arcari on 26 May 2022, 20:31:40 UTC, committed by Hans de Goede on 10 June 2022, 19:59:08 UTC
The probe function pmt_crashlog_probe() may incorrectly reference the 'priv->entry array' as it uses 'i' to reference the array instead of 'priv->num_entries' as it should. This is similar to the problem that was addressed in pmt_telemetry_probe via commit 2cdfa0c20d58 ("platform/x86/intel: Fix 'rmmod pmt_telemetry' panic"). Cc: "David E.
