[PATCH] crypto: call zlib end functions on deflate exit path
In the deflate_[compress|uncompress|pcompress] functions we call the zlib_[in|de]flateReset function at the beginning. This is OK. But when we unload the deflate module we don't call zlib_[in|de]flateEnd to free all the zlib internal data. It looks like a bug for me. Please, consider the attached patch. Signed-off-by: Artem B.
