Building with 'make W=1' shows a few harmless -Wempty-body warning for the
mvsas driver:
drivers/scsi/mvsas/mv_94xx.c: In function 'mvs_94xx_phy_reset':
drivers/scsi/mvsas/mv_94xx.c:278:63: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body]
278 | mv_dprintk("phy hard reset failed.\n");
| ^
drivers/scsi/mvsas/mv_sas.c: In function 'mvs_task_prep':
drivers/scsi/mvsas/mv_sas.c:723:57: error: suggest braces around empty body in an 'else' statement [-Werror=empty-body]
723 | SAS_ADDR(dev->sas_addr));
| ^
Change the empty dprintk() macros to no_printk(), which avoids this warning
and adds format string checking.

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.
