2014-01-01iio: Fix a buffer overflow in iio_utils.h example codeCraig Markwardt
This was originally reported by Craig Markwardt on Zubair Lutfullah's blog and Zubair forwarded it to linux-iio@vger.kernel.org. No email address known. The code first counted the number of enabled channels, then created an array to hold information about them. The code that filled this array then stored whether a given element was enabled inside the array. Curriously this element was never used. Craig's patch added a local temporary variable to avoid the buffer overrun. Jonathan then removed the original enabled element of the structure as it was not needed at all.

2012-04-30staging:iio: Streamline API function namingLars-Peter Clausen
Currently we use two different naming schemes in the IIO API, iio_verb_object and iio_object_verb. E.g iio_device_register and iio_allocate_device. This patches renames instances of the later to the former. The patch also renames allocate to alloc as this seems to be the preferred form throughout the kernel. In particular the following renames are performed by the patch: iio_put_device -> iio_device_put iio_allocate_device -> iio_device_alloc iio_free_device -> iio_device_free iio_get_trigger -> iio_trigger_get iio_put_trigger -> iio_trigger_put iio_allocate_trigger -> iio_trigger_alloc iio_free_trigger -> iio_trigger_free The conversion was done with the following coccinelle patch with manual fixes to comments and documentation. <smpl> @@ @@ -iio_put_device +iio_device_put @@ @@ -iio_allocate_device +iio_device_alloc @@ @@ -iio_free_device +iio_device_free @@ @@ -iio_get_trigger +iio_trigger_get @@ @@ -iio_put_trigger +iio_trigger_put @@ @@ -iio_allocate_trigger +iio_trigger_alloc @@ @@ -iio_free_trigger +iio_trigger_free </smpl> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Acked-by: Jonathan Cameron <jic23@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2011-12-22staging:iio: Drop {mark,unmark}_in_use callbacksLars-Peter Clausen
These callbacks are currently used by the individual buffer implementations to ensure that the request_update callback is not issued while the buffer is in use. But the core already provides sufficient measures to prevent this from happening in the first place. So it is safe to remove them. There is one functional change due to this patch. Since the buffer is no longer marked as in use when the chrdev is opened, it is now possible to enable the buffer while it is opened. This did not work before, because mark_param_change did fail if the buffer was marked as in use.

2011-12-22staging:iio: Drop buffer mark_param_change callbackLars-Peter Clausen
Right now we have a mark_param_change callback in the buffer access functions struct, which should be called whenever the parameters (length, bytes per datum) of the buffer change. But it is only called when the user changes the buffer size, not when the bytes per datum change. Additionally each buffer implementation already keeps track internally whether its parameters have changed, making the call to mark_param_change after changing the buffer length redundant. Since each buffer implementation knows best when one of its parameters has changed just make tracking of this internal and drop the mark_param_change callback.

2011-12-22staging:iio: Drop the unused buffer enable() and is_enabled() callbacksLars-Peter Clausen
Currently none of the buffer implementations implements the enable() or is_enable() nor does core code try to call these. So it is safe to remove them.
