Subject: staging: vt6656: rxtx.c s:_uGetDataDuration simplify structure.
X-Git-Tag: MMI-PSA29.97-13-9~13778^2~262
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b02ccd5957281b7d2c364e5a34f3260961a691cb;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git

staging: vt6656: rxtx.c s:_uGetDataDuration simplify structure.

A value is only returned when bNeedAck is true.

Only when byDurType == DATADUR_B is different.

Remove switch statement and simplify with if structure.
