Re: [PATCH 09/10] iio:buffer: Add proper locking for iio_update_buffers()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



[...]
+int iio_update_buffers(struct iio_dev *indio_dev,
+		       struct iio_buffer *insert_buffer,
+		       struct iio_buffer *remove_buffer)
+{
+	int ret;
+
+	mutex_lock(&indio_dev->info_exist_lock);
+	mutex_lock(&indio_dev->mlock);
+
+	if (indio_dev->info == NULL)
+		return -ENODEV;

Yea, ok that happens when send patches way to late in the evening. Of course we still need to unlock here...

+	ret = __iio_update_buffers(indio_dev, insert_buffer, remove_buffer);
+
+	mutex_unlock(&indio_dev->mlock);
+	mutex_unlock(&indio_dev->info_exist_lock);
+
+	return ret;
+}
