From: Malcolm Priestley Date: Thu, 26 Sep 2013 17:57:34 +0000 (+0100) Subject: staging: vt6656: rxtx.c Move rts_cts pointer assignment to s_vGenerateTxParameter X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b9cc2fc0209ccfbc14ef56a99693a47b84599ee0;p=openwrt%2Fstaging%2Fblogic.git staging: vt6656: rxtx.c Move rts_cts pointer assignment to s_vGenerateTxParameter Move rts/cts pointers to relevant vnt_tx_data_head position. Remove old rts_cts pointers in calling functions.
