gcc-11 points out that the declaration does not match the definition:
net/bluetooth/ecdh_helper.c:122:55: error: argument 2 of type ‘const u8[32]’ {aka ‘const unsigned char[32]’} with mismatched bound [-Werror=array-parameter=]
122 | int set_ecdh_privkey(struct crypto_kpp *tfm, const u8 private_key[32])
| ~~~~~~~~~^~~~~~~~~~~~~~~
In file included from net/bluetooth/ecdh_helper.c:23:
net/bluetooth/ecdh_helper.h:28:56: note: previously declared as ‘const u8 *’ {aka ‘const unsigned char *’}
28 | int set_ecdh_privkey(struct crypto_kpp *tfm, const u8 *private_key);
| ~~~~~~~~~~^~~~~~~~~~~
Change the declaration to contain the size of the array, rather than
just a pointer.
