From beeb4ca466fa1c399d69e34c30ddf04e0b7cbefd Mon Sep 17 00:00:00 2001 From: John Crispin Date: Fri, 8 Apr 2016 00:54:05 +0200 Subject: [PATCH] net: mediatek: mtk_cal_txd_req() returns bad value The code used to also support the PDMA engine, which had 2 packet pointers per descriptor. Because of this we had to divide the result by 2 and round it up. This is no longer needed as the code only supports QDMA. Signed-off-by: John Crispin Signed-off-by: David S.
