When building for 32-bit targets, for which ssize_t is 'int' instead of
'long', there is a warning due to an incorrect format specifier:
In file included from include/linux/printk.h:610,
from include/linux/kernel.h:31,
from include/linux/clk.h:13,
from drivers/crypto/tegra/tegra-se-hash.c:7:
drivers/crypto/tegra/tegra-se-hash.c: In function 'tegra_sha_prep_cmd':
drivers/crypto/tegra/tegra-se-hash.c:343:26: error: format '%lu' expects argument of type 'long unsigned int', but argument 6 has type 'ssize_t' {aka 'int'} [-Werror=format=]
343 | dev_dbg(se->dev, "msg len %llu msg left %llu sz %lu cfg %#x",
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
...
drivers/crypto/tegra/tegra-se-hash.c:343:59: note: format string is defined here
343 | dev_dbg(se->dev, "msg len %llu msg left %llu sz %lu cfg %#x",
| ~~^
| |
| long unsigned int
| %u
cc1: all warnings being treated as errors
Use '%zd', the proper specifier for ssize_t, to resolve the warning.

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.
