Subject: [PATCH v6 01/22] drm/fb-helper: Remove unused local variable in hotplug_event()
Date: Wed, 20 May 2026 21:38:12 +0300 [thread overview]
Message-ID: <20260520-dw-hdmi-qp-scramb-v6-1-24b74603b782@collabora.com> (raw)
In-Reply-To: <20260520-dw-hdmi-qp-scramb-v6-0-24b74603b782@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.
