From 44455a6d3bcab53ae8330a009d513ade0f12c0c0 Mon Sep 17 00:00:00 2001 From: Lee Jones Date: Fri, 26 Jun 2020 07:57:35 +0100 Subject: [PATCH] regulator: tps65217-regulator: Use the returned value of tps65217_reg_read() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Until now the aforementioned return value has been ignored. Previous and current calls to tps65217_reg_read() return instantly when the value is not 0, so let's do that. Fixes the following W=1 warning: drivers/regulator/tps65217-regulator.c: In function ‘tps65217_regulator_probe’: drivers/regulator/tps65217-regulator.c:227:9: warning: variable ‘ret’ set but not used [-Wunused-but-set-variable] 227 | int i, ret; | ^~~ Signed-off-by: Lee Jones Cc: Russ Dill Cc: Keerthy Cc: AnilKumar Ch Cc: linux-omap@vger.kernel.org Link: https://lore.kernel.org/r/20200626065738.93412-7-lee.jones@linaro.org Signed-off-by: Mark Brown --- drivers/regulator/tps65217-regulator.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/drivers/regulator/tps65217-regulator.c b/drivers/regulator/tps65217-regulator.c index f2d3a4a..3f5ea02 100644 --- a/drivers/regulator/tps65217-regulator.c +++ b/drivers/regulator/tps65217-regulator.c @@ -254,6 +254,9 @@ static int tps65217_regulator_probe(struct platform_device *pdev) /* Store default strobe info */ ret = tps65217_reg_read(tps, regulators[i].bypass_reg, &val); + if (ret) + return ret; + tps->strobes[i] = val & regulators[i].bypass_mask; } -- 2.7.4
