From 70719350ca250a8397b74f416a45df3d1868a1d2 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Fri, 22 Apr 2016 15:19:53 +0200 Subject: [PATCH] i2c: mv64xxx: use clk_{prepare_enable,disable_unprepare} Instead of separately calling clk_prepare()/clk_enable(), use clk_prepare_enable(), and instead of calling clk_disable()/clk_unprepare(), use clk_disable_unprepare(). Those handy shortcuts have been introduced specifically to simplify the numerous call sites were both functions were called in sequence.
