Subject[PATCH 1/2] s390: Fix wrong size in memcmp (netiucv)
Date
This error was reported by cppcheck:
drivers/s390/net/netiucv.c:568: error: Using sizeof for array given as function argument returns the size of pointer.

sizeof(ipuser) did not result in 16 (as many programmers would have
expected) but sizeof(u8 *), so it is 4 or 8, too small here.
