Subject: [lm-sensors] hwmon/f75375s.c: buggy if()
Date: Wed, 17 Oct 2007 19:54:39 +0000	[thread overview]
Message-ID: <20071017195439.GD3778@stusta.de> (raw)

drivers/hwmon/f75375s.c contains the following code:

<--  snip  -->

...
static ssize_t set_pwm_mode(struct device *dev, struct device_attribute *attr,
                const char *buf, size_t count)
{
...
        if (val != 0 || val != 1 || data->kind = f75373)
                return -EINVAL;
...

<--  snip  -->

I'm not sure what exactly was intended, but it was for sure not intended 
to always return -EINVAL...

Spotted by the Coverity checker.

        of the darkness. There had been need of rain for many days.
       "Only a promise," Lao Er said.
