From: Nathan Chancellor Date: Thu, 26 Mar 2026 01:20:30 +0000 (-0700) Subject: modpost: Declare extra_warn with unused attribute X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=deb4605671cfae3b2803cfbbf4739e7245248398;p=thirdparty%2Fkernel%2Flinux.git modpost: Declare extra_warn with unused attribute A recent strengthening of -Wunused-but-set-variable (enabled with -Wall) in clang under a new subwarning, -Wunused-but-set-global, points out an unused static global variable in scripts/mod/modpost.c: scripts/mod/modpost.c:59:13: error: variable 'extra_warn' set but not used [-Werror,-Wunused-but-set-global] 59 | static bool extra_warn; | ^ This variable has been unused since commit 6c6c1fc09de3 ("modpost: require a MODULE_DESCRIPTION()") but that is expected, as there are currently no extra warnings at W=1 right now. Declare the variable with the unused attribute to make it clear to the compiler that this variable may be unused.
