Subject: [PATCH] clk: sprd: Use IS_ERR() to validate the return value of syscon_regmap_lookup_by_phandle()
Git-commit: 9629dbdabd1983ef53f125336e1d62d77b1620f9
Patch-mainline: v5.5-rc1
References: git-fixes
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().
Fixes: d41f59fd92f2 ("clk: sprd: Add common infrastructure")
