Subject: staging: vt6656: rxtx.c : s_bPacketToWirelessUsb remove usbPacketBuf.
X-Git-Tag: MMI-PSA29.97-13-9~13778^2~255
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d0a2b8fa7663a09b66f54b77dbbf460fb762aa7d;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git

staging: vt6656: rxtx.c : s_bPacketToWirelessUsb remove usbPacketBuf.

Move vnt_tx_buffer *pTxBufHead to argument u8 *usbPacketBuf position.

Fix the calling to s_bPacketToWirelessUsb so it attached to
the calling struct vnt_tx_buffer pTX_Buffer.
