A\ntable that advertises one optional argument and supplies only a\nrecognized option name, for example \"cache_mode\", reaches\nparse_cache_opts() with argc == 1.  The parser consumes the name,\ndecrements argc to zero, then calls dm_shift_arg() again for the value.\ndm_shift_arg() returns NULL when no arguments remain, and the following\nstrcmp() dereferences that NULL pointer.\n\nCheck that each recognized option has a value before consuming it.  This\nkeeps valid \"cache_mode writeback\" and \"data_crc true/false\" tables\nunchanged while making malformed tables fail during target construction\nwith a precise missing-value error."
