Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes, in particular in the
context in which this code is being used.
So, change the following form:
sizeof(*tbl) + num_entries * sizeof(struct wmi_bss_roam_info)
to :
struct_size(tbl, info, num_entries)
This code was detected with the help of Coccinelle.
