Tong Zhang 1f50392650 crypto: qat - ADF_STATUS_PF_RUNNING should be set after adf_dev_init ... [ Upstream commit 8609f5cfdc872fc3a462efa6a3eca5cb1e2f6446 ] ADF_STATUS_PF_RUNNING is (only) used and checked by adf_vf2pf_shutdown() before calling adf_iov_putmsg()->mutex_lock(vf2pf_lock), however the vf2pf_lock is initialized in adf_dev_init(), which can fail and when it fail, the vf2pf_lock is either not initialized or destroyed, a subsequent use of vf2pf_lock will cause issue. To fix this issue, only set this flag if adf_dev_init() returns 0.
