static ssize_t bcm43xx_attr_interfmode_show(struct device *dev,
                                            struct device_attribute *attr,
                                            char *buf)
{
...
        err = 0;

        bcm43xx_unlock(bcm, flags);

        return err ? err : count;

}
...
static ssize_t bcm43xx_attr_preamble_show(struct device *dev,
                                          struct device_attribute *attr,
                                          char *buf)
{
...
        err = 0;
        bcm43xx_unlock(bcm, flags);

        return err ? err : count;
}
...
static ssize_t bcm43xx_attr_preamble_store(struct device *dev,
                                           struct device_attribute *attr,
                                           const char *buf, size_t count)

        err = 0;
        bcm43xx_unlock(bcm, flags);

        return err ? err : count;
