Issue with modifying stmicro device driver to support IgH

Hello,

I’m currently facing an issue while modifying the stmmac device driver to support IgH on my system.

However, upon loading this modified kernel module, I encountered a system error indicating a null pointer causing a mem abort. I understand that the issue lies within my code, but I’m uncertain about the necessary modifications to rectify it. I would greatly appreciate if someone could provide guidance or use this as a sample to help me resolve the problem.

I appreciate your attention to this matter and look forward to working together in resolving the support requirements for stmmac devices. Please feel free to reach out for any further information or clarification.

Thank you.

Best regards
