Re: [PATCH] net: systemport: Fix ordering in intrl2_*_mask_clear macro

Since we keep shadow copies of which interrupt sources are enabled
through the intrl2_*_mask_{set,clear} macros, make sure that the
ordering in which we do these two operations: update the copy, then
unmask the register is correct.

This is not currently a problem because we actually do not use them, but
we will in a subsequent patch optimizing register accesses, so better be
safe here.

David,

This is intentionally targetting the "net-next" tree since it is
not yet a problem, yet this is still technically a bugfix. No need
to backport this to -stable or anything.

Fair enough, applied to net-next.

Thanks!
