From 8115b750dbcbeb3aa412f18b7a8b0aee4d35b079 Mon Sep 17 00:00:00 2001 From: Andy Gospodarek Date: Tue, 9 Jan 2018 16:06:19 -0500 Subject: [PATCH] net/dim: use struct net_dim_sample as arg to net_dim Simplify the arguments net_dim() by formatting them into a struct net_dim_sample before calling the function.
