Subject: Bluetooth: make hci_test_bit's addr const
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9391976a4da0d2a30abdb8d2704cfc7bf4bf9aab;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

Bluetooth: make hci_test_bit's addr const

gcc5 warns about passing a const array to hci_test_bit which takes a
non-const pointer:
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)
                   ^

So make 'addr' 'const void *'.
