Subject: [PATCH 2/6] target: tcm_loop: Improve a size determination in two
 functions

From: Markus Elfring <elfring@...rs.sourceforge.net>

Replace the specification of data structures by pointer dereferences
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.
