Nathan Chancellor 7b6092ee7a crypto: qce - revert "use __free() for a buffer that's always freed" 
Commit ce8fd0500b ("crypto: qce - use __free() for a buffer that's
always freed") introduced a buggy use of __free(), which clang
rightfully points out:

  drivers/crypto/qce/sha.c:365:3: error: cannot jump from this goto statement to its label
    365 |                 goto err_free_ahash;
        |                 ^
  drivers/crypto/qce/sha.c:373:6: note: jump bypasses initialization of variable with __attribute__((cleanup))
    373 |         u8 *buf __free(kfree) = kzalloc(keylen + QCE_MAX_ALIGN_SIZE,
        |             ^

Jumping over a variable declared with the cleanup attribute does not
prevent the cleanup function from running; instead, the cleanup function
is called with an uninitialized value.

Moving the declaration back to the top function with __free() and a NULL
initialization would resolve the bug but that is really not much
different from the original code. Since the function is so simple and
there is no functional reason to use __free() here, just revert the
original change to resolve the issue.

README 

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

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

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.
