From a2745c88032e27b16d0f78748175365601dd5107 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Marek=20Beh=C3=BAn?= Date: Tue, 24 Apr 2018 17:21:17 +0200 Subject: [PATCH] phy: marvell: a3700: Use reg_set_indirect istead of 2 reg_sets Create a special function for indirect register setting, reg_set_indirect, and use it instead of the two calls to reg_set.
