iio:accel:kxsd9 fix missing mutex unlock

2013-12-04T19:05:54Z

commit 0ee005c7dc2803125275e24598f0fb37775a6af3 upstream. This will leave a lock held after reading from the device, preventing any further reads. Signed-off-by: Frank Zago Signed-off-by: Jonathan Cameron Signed-off-by: Greg Kroah-Hartman

iio:buffer: Free active scan mask in iio_disable_all_buffers()

2013-10-15T18:26:43Z

Usually the active scan mask is freed in __iio_update_buffers() when the buffer is disabled. But when the device is still sampling when it is removed we'll end up disabling the buffers in iio_disable_all_buffers(). So we also need to free the active scan mask here, otherwise it will be leaked. Signed-off-by: Lars-Peter Clausen Signed-off-by: Jonathan Cameron

iio: frequency: adf4350: add missing clk_disable_unprepare() on error in adf4350_probe()

2013-10-12T12:20:46Z

Add the missing clk_disable_unprepare() before return from adf4350_probe() in the error handling case. Signed-off-by: Wei Yongjun Reviewed-by: Lars-Peter CLausen Signed-off-by: Jonathan Cameron

iio: Remove debugfs entries in iio_device_unregister()

2013-09-30T20:46:10Z

Remove the the debugfs entries in iio_device_unregister(). Otherwise the debugfs entries might still be accessible even though the device used in the debugfs callback has already been freed. Signed-off-by: Lars-Peter Clausen Signed-off-by: Jonathan Cameron

iio: amplifiers: ad8366: Remove regulator_put

2013-09-28T10:49:45Z

Since devm_regulator_get is used, regulator_put should not be used. Remove it. Signed-off-by: Sachin Kamat Signed-off-by: Jonathan Cameron

iio:buffer_cb: Add missing iio_buffer_init()

2013-09-21T11:52:50Z

Make sure to properly initialize the IIO buffer data structure. Signed-off-by: Lars-Peter Clausen Signed-off-by: Jonathan Cameron

iio: Prevent race between IIO chardev opening and IIO device free

2013-09-21T11:50:23Z

Set the IIO device as the parent for the character device We need to make sure that the IIO device is not freed while the character device exists, otherwise the freeing of the IIO device might race against the file open callback. Do this by setting the character device's parent to the IIO device, this will cause the character device to grab a reference to the IIO device and only release it once the character device itself has been removed. Also move the registration of the character device before the registration of the IIO device to avoid the (rather theoretical case) that the IIO device is already freed again before we can add the character device and grab a reference to the IIO device. We also need to move the call to cdev_del() from iio_dev_release() to iio_device_unregister() (where it should have been in the first place anyway) to avoid a reference cycle. As iio_dev_release() is only called once all reference are dropped, but the character device holds a reference to the IIO device. Signed-off-by: Lars-Peter Clausen Signed-off-by: Jonathan Cameron

iio: fix: Keep a reference to the IIO device for open file descriptors

2013-09-21T11:45:07Z

Make sure that the IIO device is not freed while we still have file descriptors for it. Signed-off-by: Lars-Peter Clausen Signed-off-by: Jonathan Cameron

iio: Stop sampling when the device is removed

2013-09-21T11:36:30Z

Make sure to stop sampling when the device is removed, otherwise it will continue to sample forever. Signed-off-by: Lars-Peter Clausen Signed-off-by: Jonathan Cameron
