[PATCH] drm/vc4: Fix refcount leak in vc4_hvs_bind

From: Miaoqian Lin
Date: Tue Dec 20 2022 - 06:26:02 EST


rpi_firmware_get() takes refcount, we should release it with
rpi_firmware_put(), add missing rpi_firmware_put() in the error path.

Fixes: 2a001ca00ad5 ("drm/vc4: hdmi: Rework hdmi_enable_4kp60 detection code")
