[PATCH] iio: trigger: stm32-lptimer-trigger: remove unneeded platform_set_drvdata()

[Andrei Coardos]

This function call was found to be unnecessary as there is no equivalent
platform_get_drvdata() call to access the private data of the driver. Also,
the private data is defined in this driver, so there is no risk of it being
accessed outside of this driver file.

this can become now:

            return stm32_lptim_setup_trig(priv);

I made that change whilst applying.

Applied to the togreg branch of iio.git and pushed out as testing for
the autobuilders to take a look at it and see if they can find anything
we missed.
