x86 EDAC, sb_edac.c: Repair damage introduced when "fixing" channel address
commit ff15e95c upstream. In commit: eb1af3b7 ("Fix computation of channel address") I switched the "sck_way" variable from holding the log2 value read from the h/w to instead be the actual number. Unfortunately it is needed in log2 form when used to shift the address.
