H A D | iio-trig-interrupt.c | 10e840df Thu Jan 19 21:47:38 CST 2017 Alison Schofield <amsfield22@gmail.com> iio: trigger: free trigger resource correctly
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.
