2017-08-22iio:triggers: drop assign iio_info.driver_module and iio_trigger_ops.ownerJonathan Cameron
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. Note that stm32-timer-trigger has expanded rather beyond triggers (to include encoder input counting for example) and hence has an iio_info structure.

2017-01-22iio: trigger: free trigger resource correctlyAlison Schofield
These stand-alone trigger drivers were using iio_trigger_put() where they should have been using iio_trigger_free(). The iio_trigger_put() adds a module_put which is bad since they never did a module_get. In the sysfs driver, module_get/put's are used as triggers are added & removed. This extra module_put() occurs on an error path in the probe routine (probably rare). In the bfin-timer & interrupt trigger drivers, the module resources are not explicitly managed, so it's doing a put on something that was never get'd. It occurs on the probe error path and on the remove path (not so rare). Tested with the sysfs trigger driver. The bfin & interrupt drivers were build tested & inspected only.

2014-08-26iio: remove .owner field for driver using module_platform_driverSanjeev Sharma
This patch removes the .owner field for drivers which use the platform_driver_register api because this is overriden in _platform_driver_register. Signed-off-by: Sanjeev Sharma <Sanjeev_Sharma@mentor.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

2013-06-08iio:trigger:interrupt fix formatting of rsize variable in nameJonathan Cameron
The name includes irq_res->start which of type resource_size_t not integer. We could in theory use %pa for this but then it would be in hex and also that causes a warning about incorrect types anyway. Hence just use the irq local variable we assigned the line above.
