Replace int -> uint to avoid signed integer overflow
An example of such an error (should be compiled with DEBUG_SANITIZE): runtime error: left shift of 1 by 31 places cannot be represented in type 'int' Signed-off-by: Rostislav Skudnov <rostislav@tuxera.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
