From: Hans de Goede <hdegoede@redhat.com> stable inclusion from linux-4.19.207 commit c1c3b899fb5d481c2a0ea99f259be44b1115e209 -------------------------------- [ Upstream commit caa534c3ba40c6e8352b42cbbbca9ba481814ac8 ] When fuel_gauge_reg_readb()/_writeb() fails, report which register we were trying to read / write when the error happened. Also reword the message a bit: - Drop the axp288 prefix, dev_err() already prints this - Switch from telegram / abbreviated style to a normal sentence, aligning the message with those from fuel_gauge_read_*bit_word() Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.com> Signed-off-by: Sasha Levin <sashal@kernel.org> Signed-off-by: Yang Yingliang <yangyingliang@huawei.com> --- drivers/power/supply/axp288_fuel_gauge.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/power/supply/axp288_fuel_gauge.c b/drivers/power/supply/axp288_fuel_gauge.c index 157cf5ec6b023..1641868c345c2 100644 --- a/drivers/power/supply/axp288_fuel_gauge.c +++ b/drivers/power/supply/axp288_fuel_gauge.c @@ -158,7 +158,7 @@ static int fuel_gauge_reg_readb(struct axp288_fg_info *info, int reg) } if (ret < 0) { - dev_err(&info->pdev->dev, "axp288 reg read err:%d\n", ret); + dev_err(&info->pdev->dev, "Error reading reg 0x%02x err: %d\n", reg, ret); return ret; } @@ -172,7 +172,7 @@ static int fuel_gauge_reg_writeb(struct axp288_fg_info *info, int reg, u8 val) ret = regmap_write(info->regmap, reg, (unsigned int)val); if (ret < 0) - dev_err(&info->pdev->dev, "axp288 reg write err:%d\n", ret); + dev_err(&info->pdev->dev, "Error writing reg 0x%02x err: %d\n", reg, ret); return ret; } -- 2.25.1
