Date: Wed, 22 Jan 2020 10:30:03 +0100 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Baolin Wang <baolin.wang@...aro.org>, Stephen Boyd <sboyd@...nel.org> Subject: [PATCH 5.4 217/222] clk: sprd: Use IS_ERR() to validate the return value of syscon_regmap_lookup_by_phandle() From: Baolin Wang <baolin.wang@...aro.org> 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().
