Omit an extra message for a memory allocation failure in this function.
This issue was detected by using the Coccinelle software.

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 issue was detected by using the Coccinelle software.
