Hello Wei Ni,
This is a semi-automatic email about new static checker warnings.
The patch ce0dbf04f685: "thermal: tegra: add hw-throttle function"
from May 11, 2016, leads to the following Smatch complaint:
drivers/thermal/tegra/soctherm.c:486 throttrip_program()
warn: variable dereferenced before check 'dev' (see line 481)
drivers/thermal/tegra/soctherm.c
480 {
481 struct tegra_soctherm *ts = dev_get_drvdata(dev);
^^^
Dereference inside function.
482 int temp, cpu_throt, gpu_throt;
483 unsigned int throt;
484 u32 r, reg_off;
485
486 if (!dev || !sg || !stc || !stc->init)
^^^
Check is too late.
487 return -EINVAL;
488
regards,
dan carpenter
