From b8ae430871254f95dd81dcff01828be3f6b24a57 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Thomas=20Wei=C3=9Fschuh?= Date: Wed, 11 Jun 2025 12:33:54 +0200 Subject: [PATCH] selftests: vDSO: vdso_test_getrandom: Avoid -Wunused MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit vgetrandom_put_state() and the variable "ret" in kselftest() are unused. Drop the variable "ret". Suppress the warning for vgetrandom_put_state() as it is meant as an example for libc implementors.
