- * hex_dump_to_buffer - convert a blob of data to "hex ASCII" in memory
- * @buf: data blob to dump
- * @len: number of bytes in the @buf
- * @rowsize: number of bytes to print per line; must be 16 or 32
- * @groupsize: number of bytes to print at a time (1, 2, 4, 8; default = 1)
- * @linebuf: where to put the converted data
- * @linebuflen: total size of @linebuf, including space for terminating NUL
- * @ascii: include ASCII after the hex output
- *
- * hex_dump_to_buffer() works on one "line" of output at a time, i.e.,
- * 16 or 32 bytes of input data converted to hex + ASCII output.
- *
- * Given a buffer of u8 data, hex_dump_to_buffer() converts the input data
- * to a hex + ASCII dump at the supplied memory location.
- * The converted output is always NUL-terminated.
- *
- * E.g.:
- * hex_dump_to_buffer(frame->data, frame->len, 16, 1,
- * linebuf, sizeof(linebuf), 1);
- *
- * example output buffer:
- * 40 41 42 43 44 45 46 47 48 49 4a 4b 4c 4d 4e 4f @ABCDEFGHIJKLMNO
