It is in the datapath, and ideally there shouldn't be error checks in
datapath.
But if HW does not check for errors and doesn't recover from error
conditions, driver may prefer to get the hit and do the checks.
Not for all drivers, but for the drivers that intentionally wants do the
check, I thought having a common helper function helps but I can see it
can create confusion.
@Jiawen, please continue as it is in next version, I mean have the
checks function in the driver itself.
