From 7beb620f805dcb6757b5e7870bebd75e3e9b37e0 Mon Sep 17 00:00:00 2001 From: Anson Huang Date: Thu, 1 Aug 2019 16:44:39 +0800 Subject: gpio: mxc: Use devm_clk_get_optional instead of devm_clk_get i.MX SoC's GPIO clock is optional, so it is better to use devm_clk_get_optional instead of devm_clk_get.
