Eliav Farber 4feddbe547 EDAC: Fix calculation of returned address and next offset in edac_align_ptr() 
commit f8efca92ae upstream.

Do alignment logic properly and use the "ptr" local variable for
calculating the remainder of the alignment.

This became an issue because struct edac_mc_layer has a size that is not
zero modulo eight, and the next offset that was prepared for the private
data was unaligned, causing an alignment exception.

The patch in Fixes: which broke this actually wanted to "what we
actually care about is the alignment of the actual pointer that's about
to be returned." But it didn't check that alignment.

Use the correct variable "ptr" for that.
