Subject: net/core/sock.c: quiet sparse noise
X-Git-Url: http://git.mmlx.us/?a=commitdiff_plain;h=4d0392be21d4710121f855c0caf57d32ffd1ced0;p=linux-edison.git

net/core/sock.c: quiet sparse noise

In sock_getsockopt the symbol 'lv' is declared as an
unsigned int type, probably due to sizeof returning a
size_t which is really an unsigned int.

This produces a sparse warning for SO_PEERNAME due to
the sock->ops->getname() call:

warning: incorrect type in argument 3 (different signedness)
   expected int *sockaddr_len
   got unsigned int *<noident>

Quiet the warning by changing the type of 'lv' to an int.
