Hi all,

After merging the bluetooth tree, today's linux-next build (x86_64
allmodconfig) produced this warning:

drivers/bluetooth/btmtksdio.c: In function 'btmtksdio_interrupt':
drivers/bluetooth/btmtksdio.c:470:2: warning: 'old_len' may be used uninitialized in this function [-Wmaybe-uninitialized]
  print_hex_dump(KERN_ERR, "err sdio rx: ", DUMP_PREFIX_NONE, 4, 1,
  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
          old_data, old_len, true);
          ~~~~~~~~~~~~~~~~~~~~~~~~
drivers/bluetooth/btmtksdio.c:376:15: note: 'old_len' was declared here
  unsigned int old_len;
               ^~~~~~~
drivers/bluetooth/btmtksdio.c:470:2: warning: 'old_data' may be used uninitialized in this function [-Wmaybe-uninitialized]

  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
          old_data, old_len, true);
          ~~~~~~~~~~~~~~~~~~~~~~~~
drivers/bluetooth/btmtksdio.c:375:17: note: 'old_data' was declared here
  unsigned char *old_data;
                 ^~~~~~~~
