* iio:st_gyro: Remove redundant call to iio_sw_buffer_preenable().Lars-Peter Clausen2013-10-161-10/+1
| | | | | | | | | The equivalent of iio_sw_buffer_preenable() is now done in the IIO buffer core, so there is no need to do this from the driver anymore. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Cc: Denis Ciocca <denis.ciocca@st.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

| | | | | | | | | | | | Keeping Makefile and Kconfig entries in alphabetical order usually works better than just appending new entries at the end, since it reduces the amount of conflicts. This patch adds a comment to the IIO Kconfig and Makefile files to document that the entries should be kept in alphabetical order. Also reorder those entries which weren't in alphabetical order yet.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce iio_tigger_{set,get}_drvdata which allows to attach driver specific data to a trigger. The functions wrap access to the triggers private_data field and all current users are updated to use iio_tigger_{set,get}_drvdata instead of directly accessing the private_data field. This is the first step towards removing the private_data field from the iio_trigger struct.
