Subject[PATCH 5.10 131/563] staging: rtl8192e: return error code from rtllib_softmac_init()
Date
From: Yang Yingliang <yangyingliang@huawei.com>

[ Upstream commit 68bf78ff59a0891eb1239948e94ce10f73a9dd30 ]

If it fails to allocate 'dot11d_info', rtllib_softmac_init()
should return error code. And remove unneccessary error message.
