参数：

类型参数名称
char *buf
char *end
struct fwnode_handle *fwnode
struct printf_specspec
const char *fmt
2036  str_spec等于spec
2037  buf_start等于buf
2039  width of output field 等于负1
2041  如果fmt不等于'w'则返回:Be careful: error messages must fit into the given buffer.
2044  如果check_pointer( & buf, end, fwnode, spec)则返回:buf
2047  fmt自加
2050  当:fmt恒等于'P'
2051  buf等于string(buf, end, fwnode_get_name(fwnode), str_spec)
2052  退出
2053  当:fmt恒等于'f'
2054  默认
2055  buf等于fwnode_full_name_string(fwnode, buf, end)
2056  退出
