[PATCH RESEND] sparc: PCI: Replace deprecated strcpy() with strscpy()
Posted by Thorsten Blum 4 months, 3 weeks ago 
strcpy() is deprecated; use strscpy() instead.

No functional changes intended.

No objection from me, but no particular PCI core issue and I don't
maintain this file, so up to the sparc folks if they want it.

I would consider making a single patch to address this issue
everywhere in arch/sparc so it can all be reviewed together.

Thank you and sorry for the late feedback. I agree with the above.
Thorsten, could you fix this for all occurrences of strcpy() in
arch/sparc?

Thanks,
Andreas

I just submitted a small series [1] replacing all occurrences of strcpy
in arch/sparc.

Thanks,
