[PATCH 4.14 15/61] crypto: cavium/zip - Add missing single_release()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Wei Yongjun <weiyongjun1@xxxxxxxxxx>

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")
