From 21cae8debc6a1d243f64fa82cd1b41cb612b5c61 Mon Sep 17 00:00:00 2001 From: Yuan Can Date: Wed, 6 Nov 2024 09:35:41 +0800 Subject: [PATCH] drm/amdkfd: Fix wrong usage of INIT_WORK() In kfd_procfs_show(), the sdma_activity_work_handler is a local variable and the sdma_activity_work_handler.sdma_activity_work should initialize with INIT_WORK_ONSTACK() instead of INIT_WORK().
