> Commit ac0126a01735 ("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.
