Use this version for your next submission pls: --- From: Manivannan Sadhasivam <manivannan.sadhasivam@xxxxxxxxxx> Date: Wed, 28 Dec 2022 14:10:12 +0530 Subject: [PATCH] EDAC/device: Respect any driver-supplied workqueue polling value The EDAC drivers may optionally pass the poll_msec value. Use that value if available, else fall back to 1000ms.
