Hello Arnd Bergmann,
This is a semi-automatic email about new static checker warnings.
The patch 4eef6cbfcc03: "Input: eeti_ts: pass gpio value instead of
IRQ" from Apr 30, 2012, leads to the following Smatch complaint:
drivers/input/touchscreen/eeti_ts.c:209 eeti_ts_probe()
warn: variable dereferenced before check 'pdata' (see line 202)
drivers/input/touchscreen/eeti_ts.c
201 priv->input = input;
202 priv->irq_gpio = pdata->irq_gpio;
^^^^^^^^^^^^^^^
203 priv->irq = gpio_to_irq(pdata->irq_gpio);
^^^^^^^^^^^^^^^
204
205 err = gpio_request_one(pdata->irq_gpio, GPIOF_IN, client->name);
^^^^^^^^^^^^^^^
New dereferences.
206 if (err < 0)
207 goto err1;
208
209 if (pdata)
^^^^^
Old check.
210 priv->irq_active_high = pdata->irq_active_high;
211
regards,
dan carpenter
