From a31414e8c98dadbe0d31804804090e78ab1e0e9f Mon Sep 17 00:00:00 2001 From: YueHaibing Date: Sat, 9 Nov 2019 11:42:26 +0800 Subject: clk: tegra: Use match_string() helper to simplify the code match_string() returns the array index of a matching string. Use it instead of the open-coded implementation.
