Subject: mfd: dereferencing first then checking
Date: Mon, 08 Mar 2010 12:55:22 +0000 [thread overview]
Message-ID: <20100308125522.GA11530@bicker> (raw)
drivers/mfd/t7l66xb.c +371 t7l66xb_probe(58) warn: variable dereferenced before check 'pdata'
338 t7l66xb->irq_base = pdata->irq_base;
[snip]
371 if (pdata && pdata->enable)
372 pdata->enable(dev);
Can pdata be null here? We dereferenced on line 338 without checking.
regards,
dan carpenter
