[PATCH] lib: fwts_smbios: fix portability warning from cppcheck on void * cast

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

Minor fix, ensure we don't do void * pointer arithmetic as the behaviour
is undefined (even though most compilers assume it is a char * sized).
Cast to char * before doing the addition.
