Hello Javier Martinez Canillas,
This is a semi-automatic email about new static checker warnings.
The patch 4065d1e7b216: "Input: add Cypress TTSP capacitive
multi-touch screen support" from Jan 31, 2012, leads to the following
Smatch complaint:
drivers/input/touchscreen/cyttsp_core.c +526 cyttsp_probe()
warn: variable dereferenced before check 'dev' (see line 521)
drivers/input/touchscreen/cyttsp_core.c
520 {
521 const struct cyttsp_platform_data *pdata = dev->platform_data;
^^^^^
dereference.
522 struct cyttsp *ts;
523 struct input_dev *input_dev;
524 int error;
525
526 if (!dev || !bus_ops || !pdata || !pdata->name || irq <= 0) {
^^^^
check.
527 error = -EINVAL;
528 goto err_out;
"dev" is never NULL here so the check can be removed probably.
regards,
dan carpenter
