6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yuan Can <yuancan@xxxxxxxxxx>
[ Upstream commit 21cae8debc6a1d243f64fa82cd1b41cb612b5c61 ]
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")
