[PATCH 10/13] sysfs: do not use print_symbol()

[sergey.senozhatsky.work@gmail.com (Sergey Senozhatsky)]

print_symbol() uses extra stack space to sprintf() symbol
information and then to feed that buffer to printk()

  char buffer[KSYM_SYMBOL_LEN];

  sprint_symbol(buffer, address);
  printk(fmt, buffer);

Replace print_symbol() with a direct printk("%pS") call.
