David, what if I used the __nonstring attribute from
include/linux/compiler_attributes.h which defines the following

#if __has_attribute(__nonstring__)
# define __nonstring                    __attribute__((__nonstring__))
#else
# define __nonstring
#endif

Which I came across from
https://www.kernel.org/doc/html/latest/process/programming-language.html#attributes
Also the checkpatch.pl scripts suggests using that instead.

I guess this would work from older compilers as well.
