From 7c6aa25db481f0c6e83ddf358001894a62ca294c Mon Sep 17 00:00:00 2001 From: Michal Kazior Date: Tue, 26 Aug 2014 19:14:03 +0300 Subject: [PATCH] ath10k: dont duplicate service-pipe mapping The mapping is already defined in a structure. It makes little sense to duplicate information stored in it within a function.
