From 97ccc3a6bead88e637c0150b19aaea27387ba6f7 Mon Sep 17 00:00:00 2001 From: Jes Sorensen Date: Fri, 16 May 2014 10:05:05 +0200 Subject: [PATCH] staging: rtl8723au: Clean up usb_{read,write}_port() usage Get rid of silly HAL convolution for calling usb_{read,write}_port() functions. Benefit from fact we just have one input address for read_port, so no point storing this and carrying it around. Pick pipe in the local function instead of based on dst/src address.
