Subject: [PATCH 02/12] driver: fix missing va_end in dev_add_alias error path
Date: Mon, 16 Feb 2026 09:42:18 +0100 [thread overview]
Message-ID: <20260216084253.3547270-2-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20260216084253.3547270-1-a.fatoum@pengutronix.de>
dev_add_alias() calls va_start(va, fmt) but returns -ENOMEM without
calling va_end(va) if the allocation fails.
Add the missing va_end(va) call before the error return.
Fixes: d914ef13a9 ("driver: add support for device aliases")
Reported-by: GCC 14.2 -fanalyzer
