* staging: iio: error case memory leak fixAndre Bartke2011-06-071-3/+7
| | | | | | | | | The data pointer should be freed in the error cases of adis16400_trigger_handler(). Signed-off-by: Andre Bartke <andre.bartke@gmail.com> Acked-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* staging:iio: poll func allocation clean up.Jonathan Cameron2011-05-191-14/+9
| | | | | | | | Add a function to neatly deal with allocation of poll functions. Ultimately this allows us to more easily change the implementation. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* staging:iio: rationalization of different buffer implementation hooks.Jonathan Cameron2011-05-191-6/+10
| | | | | | | | | | | | | 1) move a generic helper function out of ring_sw. It applies to other buffers as well. 2) Get rid of a lot of left over function definitions. 3) Move all the access functions into static structures. 4) Introduce and use a static structure for the setup functions, preenable etc. Some driver conversions thanks to Michael Hennerich (pulled out of patches that would otherwise sit after this).

| | | | | | | | | | iio_dev. Uses the iio_allocate_device parameter to set aside space for adis16400_state and ____cacheline_aligned buffers for tx and rx to avoid separatel allocating them. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* staging:iio:imu:adis16350 etc support into adis16400 driver.Jonathan Cameron2011-05-191-19/+70
| | | | | | | | | | | | | | | Next patch will remove the current adis16350 driver. These should have been merged a long time ago, but there we are. V3: rebase fixup + add missing extend_name for supply on adis16350 V2: Move to single IIO_CHAN macro + use the new extend_name to make the naming of the temperature sensors contain x, y, z rather than messing with modifiers. This a very weird case and I don't want temperature to use axial modifiers. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* Staging: iio: pull in slab.h for kmalloc funcsMike Frysinger2010-06-181-0/+1
| | | | | | | | | | These drivers use kzalloc() but don't include slab.h. They currently build though because the spi.h header will pull in slab.h for us. But rather than rely on that behavior forever, include slab.h explicitly.
