fix(rifsc): remove unused parameter in stm32_rifsc_register_debugfs when DEBUG_FS is not set

[JocelynMeyron-eaton]

This is the error I got when I compile the kernel without the CONFIG_DEBUG_FS option:

| ../../../../../../kernel-source/drivers/bus/stm32_rifsc.c:636:68: error: expected ';', ',' or ')' before '__unused'
|   636 | static int stm32_rifsc_register_debugfs(struct rifsc_private *priv __unused)
|       |                                                                    ^~~~~~~~

|       |              ^~~~~~~~~~~~~~~~~~~~~~~~~~~~

Feel free to forward this fix to your internal team if you don't want to merge my PR.

Hello Jocelyn,

Thank you for reporting this build error. Indeed, your patch is perfectly fine. Unfortunately, we cannot merge patches in this repository.
I will create a patch in our downstream for the next release. Would you like to share an e-mail address so I can add a Reported-by: tag or you don't care?

Thanks,
