+Subject: [PATCH 09/15] rt2x00usb: remove unnecessary rx flag checks
+
+In contrast to the TX path, there is no need to separately read the transfer
+status from the device after receiving RX data. Consequently, there is no
+real STATUS_PENDING RX processing queue entry state.
+Remove the unnecessary ENTRY_DATA_STATUS_PENDING flag checks from the RX path.
+Also remove the misleading comment about reading RX status from device.
