From 80b61046b6899c6e881ff191aa99256d8e43cd58 Mon Sep 17 00:00:00 2001 From: David Laight Date: Wed, 19 Nov 2025 22:41:33 +0000 Subject: [PATCH] crypto: lib/mpi - use min() instead of min_t() min_t(unsigned int, a, b) casts an 'unsigned long' to 'unsigned int'. Use min(a, b) instead as it promotes any 'unsigned int' to 'unsigned long' and so cannot discard significant bits. In this case the 'unsigned long' value is small enough that the result is ok. Detected by an extra check added to min_t().
