Message-ID: <20160402055045.GA23902@mwanda> (raw)
Hello Wei Ni,
This is a semi-automatic email about new static checker warnings.
The patch ee6d79f202a4: "thermal: tegra: add thermtrip function" from
Mar 29, 2016, leads to the following Smatch complaint:
drivers/thermal/tegra/soctherm.c:226 thermtrip_program()
warn: variable dereferenced before check 'dev' (see line 222)
drivers/thermal/tegra/soctherm.c
221 {
222 struct tegra_soctherm *ts = dev_get_drvdata(dev);
^^^^^^^^^^^^^^^^^^^
Dereference inside function.
223 int temp;
224 u32 r;
225
226 if (!dev || !sg)
^^^^
Too late.
227 return -EINVAL;
228
regards,
dan carpenter
