Commitac0126a017("soc: qcom: cmd-db: replace strncpy() with strscpy_pad()") breaks booting on my sc7280-herobrine-herobrine device. From printouts I see that at bootup the function is called with an id of "lnbclka2" which is 8 bytes big. Previously all 8 bytes of this string were copied to the destination. Now only 7 bytes will be copied since strscpy_pad() saves a byte for '\0' termination. We don't need the '\0' termination in the destination. Let's go back to strncpy(). According to the warning: If a caller is using non-NUL-terminated strings, strncpy() can still be used, but destinations should be marked with the __nonstring attribute to avoid future compiler warnings. ...so we'll do that. While we're at it, let's change the query array to use "sizeof(ent->id)" so it can't possibly go out of sync with our later copy.

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.
