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.
|
||
