From 7fabffed536484f5bdf67c2a1eb39a116c567f06 Mon Sep 17 00:00:00 2001 From: Baolin Wang Date: Tue, 8 Oct 2019 15:41:38 +0800 Subject: [PATCH] clk: sprd: Use IS_ERR() to validate the return value of syscon_regmap_lookup_by_phandle() commit 9629dbdabd1983ef53f125336e1d62d77b1620f9 upstream. The syscon_regmap_lookup_by_phandle() will never return NULL, thus use IS_ERR() to validate the return value instead of IS_ERR_OR_NULL().
