The custom rpr0521_trigger_consumer_store_time() is registered as trigger handler in the devm_iio_triggered_buffer_setup() function. This function is called from the calling of the iio_trigger_poll() used in the sysfs/hrt triggers and it is not used anywhere else in this driver. The irq handler of the driver is the rpr0521_drdy_irq_handler() which saves the timestamp and then wakes the irq thread. The irq thread is the rpr0521_drdy_irq_thread() function which checks if the irq came from the sensor and wakes up the trigger threaded handler through iio_trigger_poll_nested() or returns IRQ_NONE in case the irq didn't come from this sensor. This means that in the current driver, you can't reach the rpr0521_trigger_consumer_store_time() when the device's irq is triggered. This means that the extra check of iio_trigger_using_own() is redundant since it will always be false so the general iio_pollfunc_store_time() can be used.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
