Kernel test robot reported a few trucation warnings at the snprintf:
drivers/iommu/arm/arm-smmu-v3/tegra241-cmdqv.c:
In function ‘tegra241_vintf_free_lvcmdq’:
drivers/iommu/arm/arm-smmu-v3/tegra241-cmdqv.c:239:56:
warning: ‘%u’ directive output may be truncated writing between 1 and
5 bytes into a region of size between 3 and 11 [-Wformat-truncation=]
239 | snprintf(header, hlen, "VINTF%u: VCMDQ%u/LVCMDQ%u: ",
| ^~
drivers/iommu/arm/arm-smmu-v3/tegra241-cmdqv.c:239:32: note: directive argument

drivers/iommu/arm/arm-smmu-v3/tegra241-cmdqv.c:239:9: note: ‘snprintf’ output

240 | vcmdq->vintf->idx, vcmdq->idx, vcmdq->lidx);
Fix by bumping up the size of the header to hold more characters.

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.
