mainline inclusion from mainline-v5.19 commit cf4ac3fe category: feature bugzilla: https://gitee.com/openeuler/intel-kernel/issues/I596WO CVE: NA Intel-SIG: commit cf4ac3fe dmaengine: idxd: fix lockdep warning on device driver removal. Incremental backporting patches for DSA/IAA on Intel Xeon platform. -------------------------------- Jacob reported that with lockdep debug turned on, idxd_device_driver removal causes kernel splat from lock assert warning for idxd_device_wqs_clear_state(). Make sure idxd_device_wqs_clear_state() holds the wq lock for each wq when cleaning the wq state. Move the call outside of the device spinlock.
