iwlegacy: convert hex_dump_to_buffer() to %*ph
There is no need to use hex_dump_to_buffer() in the cases like this: hexdump_to_buffer(buf, len, 16, 1, outbuf, outlen, false); /* len <= 16 */ sprintf("%s\n", outbuf); since it maybe easily converted to simple: sprintf("%*ph\n", len, buf); Note: it seems in the case the output is groupped by 2 bytes and looks like a typo. Thus, patch changes that to plain byte stream. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
