tools: ynl-gen: always append ULL/LL to range types
32bit builds generate the following warning when we use a u32-max in range validation: warning: decimal constant 4294967295 is between LONG_MAX and ULONG_MAX. For C99 that means long long, C90 compilers are very likely to produce unsigned long (and a warning) here The range values are u64, slap ULL/LL on all of them just to avoid such noise. There's currently no code using full range validation, but it will matter in the upcoming page-pool introspection. Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
