Yes that is in my mind. I was planing to move this struct under
xe_assign_hw_err_regs once new platform support is added for SOC error
handling.
But to make things aligned can be taken care rightnow as well. Will
address in next patch.

Makes sense. WIll address in next patch.

My initial thought was also to use xarray for soc error counters. But
even if we use xarray we need to have separate identifiers to identify
which indexes in xarray are actually valid hardware error and which are
spurious interrupt. Hence found no use of using xarray, if we still need
to maintain all valid indexes.
