  "message": "libfdt: Rework/cleanup fdt_next_tag()\n\nCurrently, callers of fdt_next_tag() must usually follow the call with\nsome sort of call to fdt_offset_ptr() to verify that the blob isn\u0027t\ntruncated in the middle of the tag data they\u0027re going to process.\nThis is a bit silly, since fdt_next_tag() generally has to call\nfdt_offset_ptr() on at least some of the data following the tag for\nits own operation.\n\nThis patch alters fdt_next_tag() to always use fdt_offset_ptr() to\nverify the data between its starting offset and the offset it returns\nin nextoffset.  This simplifies fdt_get_property() which no longer has\nto verify itself that the property data is all present.\n\nAt the same time, I neaten and clarify the error handling for\nfdt_next_tag().  Previously, fdt_next_tag() could return -1 instead of\na tag value in some circumstances - which almost none of the callers\nchecked for.  Also, fdt_next_tag() could return FDT_END either because\nit encountered an FDT_END tag, or because it reached the end of the\nstructure block - no way was provided to tell between these cases.\n\nWith this patch, fdt_next_tag() always returns FDT_END with a negative\nvalue in nextoffset for an error.  This means the several places which\nloop looking for FDT_END will still work correctly - they only need to\ncheck for errors at the end.  The errors which fdt_next_tag() can\nreport are:\n\t- -FDT_ERR_TRUNCATED if it reached the end of the structure\n\t   block instead of finding a tag.\n\n\t- -FDT_BADSTRUCTURE if a bad tag was encountered, or if the\n           tag data couldn\u0027t be verified with fdt_offset_ptr().\n\nThis patch also updates the callers of fdt_next_tag(), where\nappropriate, to make use of the new error reporting.\n\nFinally, the prototype for the long gone _fdt_next_tag() is removed\nfrom libfdt_internal.h.\n\nSigned-off-by: David Gibson \u003cdavid@gibson.dropbear.id.au\u003e\n",
