Subject: [PATCH] mt76: mt7921: forbid the doze mode when coredump is in progress
Git-commit: d9bf93172f4ac6c6b766ed8ec5affcd014b95e29
Patch-mainline: v5.18-rc1
References: bsc#1209980
We forbid the doze mode while the collecting core dump is going because
that doesn't make sense and the firmware possibly stays in the abnormal
state where cannot handle the doze request from the driver anymore until
the WiFi reset procedure is completed.
