From 99e71543521ce1646fb8d3de1e68fe56a3ba5f8e Mon Sep 17 00:00:00 2001 From: Yisheng Xie Date: Thu, 31 May 2018 19:11:13 +0800 Subject: [PATCH] clk: bcm2835: use match_string() helper match_string() returns the index of an array for a matching string, which can be used instead of open coded variant.
