Subject: [PATCH] kbuild: simplify generic vdso installation code
Date: Tue, 30 Apr 2024 00:07:54 +0900 [thread overview]
Message-ID: <20240429150754.3178262-1-masahiroy@kernel.org> (raw)
With commit 4b0bf9a01270 ("riscv: compat_vdso: install compat_vdso.so.dbg
to /lib/modules/*/vdso/") applied, all debug VDSO files are installed in
$(MODLIB)/vdso/.
Simplify the installation rule.
