Subject: [PATCH] minmax: allow comparisons of 'long long int' against 'unsigned char/short/int'
Date: Mon, 8 Jan 2024 04:11:29 +0800 [thread overview]
Message-ID: <20240107201129.6106-1-zoo868e@gmail.com> (raw)
Since 'unsigned int' get promoted to 'signed long long int' it is safe
to compare them against an 'long long int' value.
