Nathan Chancellor c549355105 crypto: crypto4xx - Replace bitwise OR with logical OR in crypto4xx_build_pd
[ Upstream commit 5bdad829c31a09069fd508534f03c2ea1576ac75 ]

Clang warns:

drivers/crypto/amcc/crypto4xx_core.c:921:60: warning: operator '?:' has
lower precedence than '|'; '|' will be evaluated first
[-Wbitwise-conditional-parentheses]
                 (crypto_tfm_alg_type(req->tfm) == CRYPTO_ALG_TYPE_AEAD) ?

It looks like this should have been a logical OR so that
PD_CTL_HASH_FINAL gets added to the w bitmask if crypto_tfm_alg_type
is either CRYPTO_ALG_TYPE_AHASH or CRYPTO_ALG_TYPE_AEAD. Change the
operator so that everything works properly.

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 Restructured Text 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.
