2018-05-22iio: amplifiers: ad8366: move channel init before iio_device_register()Alexandru Ardelean1-2/+4
Otherwise a race condition can occur, where userspace can start operations before the channels have been properly initialized. Signed-off-by: Alexandru Ardelean <alexandru.ardelean@analog.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
2017-08-22iio:amplifiers:ad8366 drop assign iio_info.driver_module and ↵Jonathan Cameron1-1/+0
iio_trigger_ops.owner The equivalent of both of these are now done via macro magic when the relevant register calls are made. The actual structure elements will shortly go away. Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Reviewed-by: Lars-Peter Clausen <lars@metafoo.de>

2015-10-28spi: Drop owner assignment from spi_driversAndrew F. Davis1-1/+0
An spi_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Andrew F. Davis <afd@ti.com> Acked-by: Jonathan Cameron <jic23@kernel.org> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-08-22iio: Export SPI module alias information in missing driversJavier Martinez Canillas1-0/+1
The SPI core always reports the MODALIAS uevent as "spi:<modalias>" regardless of the mechanism that was used to register the device (i.e: OF or board code) and the table that is used later to match the driver with the device (i.e: SPI id table or OF match table). So drivers needs to export the SPI id table and this be built into the module or udev won't have the necessary information to autoload the needed driver module when the device is added.

2013-08-03iio: Add a comment to about alphabetical order to Kconfigs and MakefilesLars-Peter Clausen2-0/+3
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.

2013-01-04Drivers: iio: remove __dev* attributes.Greg Kroah-Hartman1-3/+3
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.
