Checks
Commit Message
From: Yunjian Wang <wangyunjian@huawei.com>

and this causes a memory leak.
Fixes: a753e53d517b ("eal: add device event monitor framework")

hi, yunjian
The patch seems no problem, but when you update your patch, please add
other guys who had comment on your patch and maintainer to see if they have
