[PATCH v1] staging: rtl8723bs: remove shadowed bDumpRxPkt declaration

[Yuho Choi]

DBG_RX_DUMP_EAP redeclares bDumpRxPkt inside validate_recv_frame(),
shadowing the existing function-local variable. Drop the inner declaration
and reuse the existing variable to avoid unnecessary shadowing.

If you trace this back, why is this variable being used at all?  Look at
how it is being used, and please explain the logic here.

Personally, I think this can be deleted entirely, but please verify
this.

thanks,

Could you explain why there are so many SOB here for such a simple
change?

Thanks,

Re: [PATCH v1] staging: rtl8723bs: remove shadowed bDumpRxPkt declaration

Dear Greg, Andy, Ethan,

Thanks for the feedback.

This patch came from an ongoing research project with my fellow
researchers, and I included
the SOBs to reflect that collaboration. After reviewing the Linux
patch submission conventions
again, I agree that these tags should be limited to people who
directly contributed to the
specific patch itself. For this patch, that attribution was too broad.
I will be more careful about
that in future submissions.

I also understand the concern about the patch itself. I will trace the
logic more carefully.

Best regards,
Yuho Choi
