This -Wsign-compare compiler warning can be very noisy and most of the suggested conversions are unnecessary. Make the warning W=3 so it's described under the "can most likely be ignored" block. Signed-off-by: Joe Perches <joe@perches.com> --- On Tue, 2020-07-21 at 14:32 -0700, Joe Perches wrote:

This patch fixes the warning: warning: comparison of integer expressions of different signedness: 'int' and 'long unsigned int' [-Wsign-compare]I think these do not really need conversion. Are these useful compiler warnings ?
Perhaps move the warning from W=2 to W=3 so it's described as "can most likely be ignored" scripts/Makefile.extrawarn | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
