Although you found this with KASAN as an out of bounds array reference,
the real problem is that the sb_edac.c driver didn't know about systems
with segmented PCI busses.

So the Subject: for the e-mail (and thus the commit message) should

[PATCH] EDAC, sb_edac: Add support for systems with segmented PCI busses

Otherwise this looks fine.
