The enum string table parameters in various QOM/QAPI methods are declared 'const char *strings[]'. This results in const warnings if passed a variable that was declared as static const char * const strings[] = { .... }; Add the extra const annotation to the parameters, since neither the string elements, nor the array itself should ever be modified.
