From 5b47d2364652979dc43df14f7af19346a001b770 Mon Sep 17 00:00:00 2001 From: Justin Stitt Date: Thu, 7 Jul 2022 11:20:52 -0700 Subject: [PATCH] net: rxrpc: fix clang -Wformat warning When building with Clang we encounter this warning: | net/rxrpc/rxkad.c:434:33: error: format specifies type 'unsigned short' | but the argument has type 'u32' (aka 'unsigned int') [-Werror,-Wformat] | _leave(" = %d [set %hx]", ret, y); y is a u32 but the format specifier is `%hx`. Going from unsigned int to short int results in a loss of data. This is surely not intended behavior. If it is intended, the warning should be suppressed through other means. This patch should get us closer to the goal of enabling the -Wformat flag for Clang builds.
