+ * get_adapter_status() can be called by the EEH handler during EEH recovery.

+ * interface rtas_get_sensor() loops over the RTAS call on extended delay
+ * return code (9902) until the return value is either success (0) or error
+ * (-1). This causes the EEH handler to get stuck for ~6 seconds before it
+ * could notify that the PCI error has been detected and stop any active
+ * operations. This sometimes causes EEH recovery to fail. To avoid this issue,
+ * invoke rtas_call(get-sensor-state) directly if the respective PE is in EEH
+ * recovery state and return -EBUSY error based on RTAS return status. This
+ * will help the EEH handler to notify the driver about the PCI error
+ * immediately and successfully proceed with EEH recovery steps.
