Chad Dupuis af59f7fdfa scsi: qedf: Fix crash when MFW calls for protocol stats while function is still probing ... [ Upstream commit ad40f52560 ] The MFW may make a call to qed and then to qedf for protocol statistics while the function is still probing. If this happens it's possible that some members of the struct qedf_ctx may not be fully initialized which can result in a NULL pointer dereference or general protection fault. To prevent this, add a new flag call QEDF_PROBING and set it when the __qedf_probe() function is active. Then in the qedf_get_protocol_tlv_data() function we can check if the function is still probing and return immediantely before any uninitialized structures can be touched.
