Pali raised some concerns around corner case scenarios that probing
may fail on dell-wmi-descriptor causing dell-wmi and dell-smbios-wmi
to be stuck in infinite deferred probing loops.
This patch series accounts for that corner case.
Changes since original submission:
- Add as second patch that catches potential NULL pointer
- Avoid potential race condition between driver init and calling
check for if validation successful
