Vincent Whitchurch a86c45d26c crypto: cryptd - Fix skcipher instance memory leak 
commit 1a0fad630e upstream.

cryptd_skcipher_free() fails to free the struct skcipher_instance
allocated in cryptd_create_skcipher(), leading to a memory leak.  This
is detected by kmemleak on bootup on ARM64 platforms:

 unreferenced object 0xffff80003377b180 (size 1024):
   comm "cryptomgr_probe", pid 822, jiffies 4294894830 (age 52.760s)
   backtrace:
     kmem_cache_alloc_trace+0x270/0x2d0
     cryptd_create+0x990/0x124c
     cryptomgr_probe+0x5c/0x1e8
     kthread+0x258/0x318

README 

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
