Subject: [PATCH 5.3 042/148] crypto: cavium/zip - Add missing single_release()
From: Wei Yongjun <weiyongjun1@...wei.com>
commit c552ffb5c93d9d65aaf34f5f001c4e7e8484ced1 upstream.
When using single_open() for opening, single_release() should be
used instead of seq_release(), otherwise there is a memory leak.
Fixes: 09ae5d37e093 ("crypto: zip - Add Compression/Decompression statistics")
