Subject: [PATCH] HSI: omap_ssi: Don't jump to free ID in ssi_add_controller()
Date: Mon, 12 Oct 2020 10:56:43 +0800 [thread overview]
Message-ID: <20201012025643.6883-1-jingxiangfeng@huawei.com> (raw)
In current code, it jumps to ida_simple_remove() when ida_simple_get()
failes to allocate an ID. Just return to fix it.
Fixes: 0fae198988b8 ("HSI: omap_ssi: built omap_ssi and omap_ssi_port into one module")
