From 4bc8daf28251e2384a06360882994d777dcf5276 Mon Sep 17 00:00:00 2001 From: Yoshiki Ito Date: Thu, 10 Feb 2022 09:14:58 +0900 Subject: Add support for evklib to use struct proc_ops Kernel 5.6 and later replaced struct file_operations with struct proc_ops. Enabling agl-refhw-h3 feature or virtio-aarch64 machine configuration will cause build errors. This patch enables kernel-module-evklib to use struct proc_ops at 5.6 and later to avoid the errors.
