2024-03-08hwrng: hisi - use dev_err_probeMartin Kaiser1-4/+2

2023-09-15hwrng: hisi - removed unneeded call to platform_set_drvdata()Andrei Coardos1-2/+0
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.
