Randy Dunlap 5deca3bb7f crypto: nx - fix build warnings when DEBUG_FS is not enabled 
BugLink: https://bugs.launchpad.net/bugs/2034918

[ Upstream commit b04b076fb56560b39d695ac3744db457e12278fd ]

Fix build warnings when DEBUG_FS is not enabled by using an empty
do-while loop instead of a value:

In file included from ../drivers/crypto/nx/nx.c:27:
../drivers/crypto/nx/nx.c: In function 'nx_register_algs':
../drivers/crypto/nx/nx.h:173:33: warning: statement with no effect [-Wunused-value]
  173 | #define NX_DEBUGFS_INIT(drv)    (0)
../drivers/crypto/nx/nx.c:573:9: note: in expansion of macro 'NX_DEBUGFS_INIT'
  573 |         NX_DEBUGFS_INIT(&nx_driver);
../drivers/crypto/nx/nx.c: In function 'nx_remove':
../drivers/crypto/nx/nx.h:174:33: warning: statement with no effect [-Wunused-value]
  174 | #define NX_DEBUGFS_FINI(drv)    (0)
../drivers/crypto/nx/nx.c:793:17: note: in expansion of macro 'NX_DEBUGFS_FINI'
  793 |                 NX_DEBUGFS_FINI(&nx_driver);

Also, there is no need to build nx_debugfs.o when DEBUG_FS is not
enabled, so change the Makefile to accommodate that.

Fixes: ae0222b728 ("powerpc/crypto: nx driver code supporting nx encryption")
Fixes: aef7b31c88 ("powerpc/crypto: Build files for the nx device driver")

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.
