Subject: [PATCH] drm/bridge: Fix free wrong object in sii8620_init_rcp_input_dev

rc_dev is allocated by rc_allocate_device(), and doesn't assigned to
ctx->rc_dev before calling rc_free_device(ctx->rc_dev).
So it should call rc_free_device(rc_dev);

Fixes: e25f1f7 ("drm/bridge/sii8620: add remote control support")
