From 6156086e554cd9837b81e77a06451b811da2216e Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Wed, 13 Sep 2023 16:08:04 +0200 Subject: [PATCH] m68k: emu: Remove unused vsnprintf() return value in nfprint() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit When building with W=1: arch/m68k/emu/natfeat.c: In function ‘nfprint’: arch/m68k/emu/natfeat.c:59:13: warning: variable ‘n’ set but not used [-Wunused-but-set-variable] 59 | int n; | ^ As the return value of vsnprintf() is unused, and serves no practical purpose here, fix this by removing the variable.
