From 933ecf591275e850a46b28c6016d2688b92e23f6 Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Sat, 1 Nov 2025 21:19:41 -0700 Subject: [PATCH] random: remove unused get_random_var_wait functions None of these functions are used, so remove them. This renders the two bugs moot: - get_random_u64_wait() used the wrong pointer type, making it provide only 32 bits. - The '#undef' directive used the wrong identifier, leaving the helper macro defined.
