Subject: [PATCH] bluetooth: hci_sock: Use type cast "(void *)" to avoid building warnings

From: Chen Gang S <gang.chen-/[email-masked]>
Date: Tue, 03 Feb 2015 04:37:49 +0800

The related warning (with allmodconfig under xtensa):

  net/bluetooth/hci_sock.c: In function 'hci_sock_sendmsg':
  net/bluetooth/hci_sock.c:955:8: warning: passing argument 2 of 'hci_test_bit' discards 'const' qualifier from pointer target type [-Wdiscarded-array-qualifiers]
          &hci_sec_filter.ocf_mask[ogf])) &&
          ^
  net/bluetooth/hci_sock.c:49:19: note: expected 'void *' but argument is of type 'const __u32 (*)[4] {aka const unsigned int (*)[4]}'
   static inline int hci_test_bit(int nr, void *addr)
                     ^
