Subject: [PATCH v1] drm: bridge: it66121: Check drm_bridge_attach retval
Date: Thu, 5 Aug 2021 20:50:39 +0200 [thread overview]
Message-ID: <20210805185039.402178-1-robert.foss@linaro.org> (raw)
The return value of drm_bridge_attach() is ignored during
the it66121_bridge_attach() call, which is incorrect.
Fixes: 988156dc2fc9 ("drm: bridge: add it66121 driver")
Signed-off-by: Robert Foss <robert.foss@linaro.org>
