Replace the specification of a data structure by a pointer dereference
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.

This patch removes the information about the device for which the allocation
fails.

>   Improve a size determination

This patch depends on the earlier patch (which is not being merged) so please
re-base it if you want it to be applied.

How do you think about to take another look if a Linux allocation failure report
could be sufficient in this use case?

Would you dare to reduce any context lines for this update step so that
such a small adjustment will still work?
