Javier Martinez Canillas 4e88768a95 hwrng: meson - Remove unneeded platform MODULE_ALIAS
The Amlogic Meson is a DT-only platform, which means the devices are
registered via OF and not using the legacy platform devices support.

So there's no need to have a MODULE_ALIAS("platform:meson-rng") since
the reported uevent MODALIAS to user-space will always be the OF one.

Javier Martinez Canillas 877f69a81e hwrng: meson - Fix module autoload for OF registration
If the driver is built as a module, autoload won't work because the module
alias information is not filled. So user-space can't match the registered
device with the corresponding module.

Export the module alias information using the MODULE_DEVICE_TABLE() macro.

Before this patch:

$ modinfo drivers/char/hw_random/meson-rng.ko | grep alias
alias:          platform:meson-rng

After this patch:

$ modinfo drivers/char/hw_random/meson-rng.ko | grep alias
alias:          platform:meson-rng
alias:          of:N*T*Camlogic,meson-rngC*
alias:          of:N*T*Camlogic,meson-rng

PrasannaKumar Muralidharan 68734bc9f5 hwrng: Remove check for max less than 4 bytes
HW RNG core never asks for data less than 4 bytes. The check whether max
is less than 4 bytes is unnecessary. Remove the check.
