Subject: [PATCH] rtw88: fix seq_file memory leak
Date: Wed, 4 Sep 2019 14:16:01 +0000 [thread overview]
Message-ID: <20190904141601.186107-1-weiyongjun1@huawei.com> (raw)
When using single_open(), single_release() should be used instead
of seq_release(), otherwise there is a memory leak.
This is detected by Coccinelle semantic patch.
Fixes: e3037485c68e ("rtw88: new Realtek 802.11ac driver")
