Subject: [PATCH] drm/amdkfd: Fix wrong usage of INIT_WORK()
Date: Wed, 6 Nov 2024 09:35:41 +0800 [thread overview]
Message-ID: <20241106013541.77666-1-yuancan@huawei.com> (raw)
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().
Fixes: 32cb59f31362 ("drm/amdkfd: Track SDMA utilization per process")
