The platform_get_drvdata call was removed in 4c04b3729 ("hwrng: bcm2835 - Use device managed helpers"). Reviewed-by: Martin Kaiser <martin@kaiser.cx>

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.
