Subject: [PATCH 0/2] Account for uncorrectable failures in probing
Date: Fri,  3 Nov 2017 11:27:20 -0500	[thread overview]
Message-ID: <cover.1509725778.git.mario.limonciello@dell.com> (raw)

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
Mario Limonciello (2):
  platform/x86: dell-wmi-descriptor: check if memory was allocated
  platform/x86: dell-*wmi*: Relay failed initial probe to dependent
    drivers
