Subject: [PATCH v7 01/30] drm/fb-helper: Remove unused local variable in hotplug_event()
Date: Tue, 02 Jun 2026 01:44:01 +0300 [thread overview]
Message-ID: <20260602-dw-hdmi-qp-scramb-v7-1-445eb54ee1ed@collabora.com> (raw)
In-Reply-To: <20260602-dw-hdmi-qp-scramb-v7-0-445eb54ee1ed@collabora.com>
Remove the 'err' local variable in drm_fb_helper_hotplug_event() which
only stores a return value that is never used beyond the immediate
return statement. This simplifies the code without behavior changes.
