soc: qcom: cmd-db: Drop NUL bytes from debugfs output
The debugfs dump of Command DB relies uses %*pEp to print the resource identifiers, with escaping of non-printable characters. But p (ESCAPE_NP) does not escape NUL characters, so for identifiers less than 8 bytes in length the output will retain these. This does not cause an issue while looking at the dump in the terminal (no known complaints at least), but when programmatically consuming the debugfs output the extra characters are unwanted. Change the fixed 8-byte sizeof() to a dynamic strnlen() to avoid printing these NUL 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 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.
