We expect slowpath_params.name to be NUL-terminated based on its future
usage with other string APIs:
| static int qed_slowpath_start(struct qed_dev *cdev,
| struct qed_slowpath_params *params)
...
| strscpy(drv_version.name, params->name,
| MCP_DRV_VER_STR_SIZE - 4);
Moreover, NUL-padding is not necessary as the only use for this slowpath
name parameter is to copy into the drv_version.name field.
Also, let's prefer using strscpy(src, dest, sizeof(src)) in two instances
(one of which is outside of the scsi system but it is trivial and related
to this patch).
We can see the drv_version.name size here:
| struct qed_mcp_drv_version {
| u32 version;
| u8 name[MCP_DRV_VER_STR_SIZE - 4];
| };

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.
