* Use a special format string specification for the desired output of the
array "val" into a sequence.
* Adjust two local variables accordingly.
This refactoring supersedes the update suggestion "tinydrm: mipi-dbi:
Use seq_putc() in mipi_dbi_debugfs_command_show()" from 2017-05-08.
https://patchwork.kernel.org/patch/9716119/
Fixes: 02dd95fe316936269a52d6ccb971bb956412b40a ("drm/tinydrm: Add MIPI DBI support")
